"In an effort to minimize the impact … we are directing affected employees to use available vacation time so they can continue to receive their pay and benefits," said Lockheed CEO Marillyn A. Hewson in a statement. "We hope that Congress and the Administration are able to resolve this situation as soon as possible."

Because of the shutdown, Kensington-based John Shorb Landscaping got a stop-work order on a contract to manage the landscapes of federal properties in D.C. and Maryland. It laid off 28 of the 32 employees whose jobs are connected to that contract.

"We're not allowed to work," said John W. Shorb, the company's president. "We also got a stop-work order for a contract we just received … for the National Arboretum."

But for some, the past week has been almost business as usual. Michael S. Rogers, CEO of Baltimore-based Securityhunter, a 15-employee federal contractor that provides security systems including video cameras and bulletproof barriers, said his staff has been able to continue working on most of the company's projects because they're deemed essential.

The Maryland Zoo in Baltimore is even getting a bit of a boost as Washington-area school groups that booked field trips to the now closed National Zoo look for alternatives. About a dozen called and several have visited.

But for many, the impact is bad, not good.

Raymond Lowder, 66, who runs his one-man concession business in the Centers for Medicare & Medicaid Services, said sales are normally low because he's stuck in an area without much foot traffic. Now they're tiny. He didn't even manage to hit the $50 mark on Tuesday, the shutdown's first day.

The Baltimore man said he barely managed as it was, and a health emergency in August put him further behind. Now this.

"It's 'Can we kick you in the back just one more time?' " he said.

Ronza Othman, who works at the Centers for Medicare and Medicaid Services, said she worries about Lowder's situation. Hers, too. She's furloughed from her job as an attorney in the agency's civil rights office, and because her paycheck covers her rent, her "tremendous" student loans and her parents' mortgage back in Chicago, she doesn't have a lot saved up.

She can't accept outside work without giving the agency's ethics office 45 days' notice, and anyway, that office also was hit by furloughs. She applied for unemployment, but those payments won't stretch far enough.

That means cutting back wherever possible, and that's where her personal misfortune ripples into the larger economy. No new cellphone. No more daily trip to a mom-and-pop coffee shop before catching the bus to work.

"I said, 'I'm one of those furloughed feds — this is going to be my last cup of coffee for a while,' " she told the staff on Tuesday.

Across the street from Fort Meade, where normally more than 50,000 people work, small-business owners wait to see what sort of hit they might have to absorb.

Ali Mamdouhi's Seven Oaks Cleaners got more business at first as temporarily out-of-work civilians ran needed errands, but he's already seeing a reversal.

"We usually dry-clean a lot of professional attire," he said. "With professionals not working, they'd have less of a need."

Veronica Scales, who owns Hair on You Salon & Spa in the same shopping center, said business has been rough since the recession — so rough she had to sell her house and rent. This past week, fewer customers made appointments and several who work for the federal government called to cancel, she said.

The last two shutdowns, nearly back-to-back in late 1995 and early 1996, stretched on for nearly 30 days in total.

"I hope it doesn't last that long this time," Scales said.

Angle's Salsa Grill was still young during those shutdowns. This time, he's not waiting around for Congress to stop arguing.

He's ordering less food for the smaller lunch crowd. He's trying to branch out into breakfast, perhaps in the coming week, in a bid to get more customers in the door.

What he'd really like, of course, is for his regulars to get back to work across the street. But that's something he can't order up.

"Wish we could," he said.
