The politicians, bureaucrats, lobbyists and interest groups in Washington are hyperventilating that the federal gravy train may get sidetracked for a day or two by a shutdown fight between Republicans and Democrats.

I’m not sure why they’re so agitated. After all, the shutdown is really just a slowdown since only non-essential bureaucrats are sent home. And everyone winds up getting paid for those unplanned vacations, which is why the bureaucrats I know are crossing their fingers for a lengthy confrontation.

But that describes what may happen when the new fiscal year begins tomorrow. What’s been happening in recent days, culminating today, is a feeding frenzy of end-of-the-fiscal-year wasteful spending.

Here are some details from a Washington Post expose.

This past week, the Department of Veterans Affairs bought $562,000 worth of artwork. In a single day, the Agriculture Department spent $144,000 on toner cartridges. And, in a single purchase, the Coast Guard spent $178,000 on “Cubicle Furniture Rehab.” …All week, while Congress fought over next year’s budget, federal workers were immersed in a separate frantic drama. They were trying to spend the rest of this year’s budget before it is too late. …If they don’t, the money becomes worthless to them on Oct. 1. And — even worse — if they fail to spend the money now, Congress could dock their funding in future years. The incentive, as always, is to spend. So they spent.

If you’re a taxpayer, you’ll be especially delighted to know that the “use it or lose it” spending orgy is so intense that federal contractors have to cater lunches for their sales staff. Can’t have them away from their desks, after all!

It was the return of one of Washington’s oldest bad habits: a blitz of expensive decisions, made by agencies with little incentive to save. Private contractors — worried that sequestration would result in a smaller spending rush this year — brought in food to keep salespeople at their desks. Federal workers quizzed harried colleagues in the hallways, asking if they had spent it all yet. …“Use it or lose it” season is not marked on any official government calendars. But in Washington, it is as real as Christmas. And as lucrative. …In 2012, for instance, the government spent $45 billion on contracts in the last week of September, according to calculations by the fiscal-conservative group Public Notice. That was more than any other week — 9 percent of the year’s contract spending money, spent in 2 percent of the year.

The IRS may win the prize for the most egregious example of last-minute waste.

In 2010, for instance, the Internal Revenue Service had millions left over in an account to hire new personnel. The money would expire at year’s end. Its solution was not a smart one. The IRS spent the money on a lavish conference. Which included a “Star Trek” parody video starring IRS managers. Which was filmed on a “Star Trek” set that the IRS paid to build. (Sample dialogue: “We’ve received a distress call from the planet NoTax.”)

But it’s not just tax collectors who flush our money down the toilet in creative ways.

One recent study, for instance, found that information technology contracts signed at year’s end often produced noticeably worse results than those signed in calmer times. …they listed dumb things they had seen bought: three years’ worth of staples. Portable generators that never got used. One said the National Guard bought so much ammunition that firing it all became a chore. “When you get BORED from shooting MACHINE GUNS, there is a problem,” an anonymous employee wrote.

Impressive examples of waste, though I confess I’m curious about the part about ammo and the National Guard. Does this mean bullets are like milk and have to be fired before an expiration date?

Beats me, but at least someone in the government acknowledged that (at least up to a point) it’s cool to fire a machine gun. Maybe that person should hook up with the Texas cop who likes tanks.

Oh, and you’ll be happy to know that spendaholic bureaucrats and crafty interest groups keep track of time zones so they can squander money until the very last second.

On Monday, Richer’s people will sell until midnight. Then they will keep selling. “Money rolls across the continent,” the feds say. Cash not spent in Washington might be spent by federal offices in California in the three hours before it is midnight there. When it is midnight in California — 3 a.m. in Washington — they will keep on. There are federal offices in Hawaii, after all. And it will still be three hours until midnight there.

Makes me think that we may need a slogan for the bureaucracy. Perhaps this modification of the Postal Service’s unofficial motto: “Neither snow nor rain nor heat nor gloom of night - nor even different time zones - stays these bureaucrats from spending every possible penny of other people’s money.”

But let’s close on an upbeat note. Whether you give credit to the Tea Party, to Republicans, to gridlock, or to Obama, the good news is that the federal government in the past two years has been wasting money at a slower rate.

So taxpayers can smile…or at least not frown as much. The bureaucracy and contractors may be throwing a party today, but not with the same reckless abandon they displayed a between 2001 and 2010.
