While I was in between jobs over a decade ago I lived next to a really nice luxury hotel with an omelette bar restaurant in the atrium. About four times / month I would put on a suit at 7:30 a.m., comb my hair, walk into the hotel past the front desk, and then discreetly head over to the elevator.

I'd take the elevator up to say the 10th floor, jump off and find someone's USA Today they hadn't yet grabbed from their doorstep. Then I would head back down to the atrium - stepping off the elevator in full suit and tie, and casually read "my" USA Today as I stood in the breakfast line.

Nobody ever questioned whether I was a guest - and I'd get these massive omelette breakfasts with parfaits on the side, toast, fresh juice, the whole 9-yards. Sometimes I'd get seconds and sneak it out the door in my briefcase for lunch.

After a few months of this the cook caught on and started giving me looks, so I stopped.
