I used to travel extensively in my work and often would get in to the hotel late, after the restaurants and room service had closed.
So I would frequently make dinner from whatever was in the room's frij--those special kind full of beer, wine, candy, etc. that automatically are charged to the room when you remove items. So what if a bottle of mixed nuts cost $19? My company was paying for it, and they're the ones who put me on a 10:00 PM flight.
Well, one night, I was famished, threw open the frij, and grabbed a bottle of nuts and a can of Heinekin. Hmmmm. The beer was open, though the top had been replaced so carefully it was not noticeable until I'd taken it out. I tasted it--water.
I pulled another beer from its charge-my-room-now mooring--same thing. And the last beer--same thing. I opened the bottle of nuts, and it was filled with brown sand--making it heavy and appear to be full of nuts--and smelled like it came from the cigarette receptacles.
I needed to eat, so I madly began ripping the rest of the food out, starting with the candy bars. Each of them had been opened and resealed with exquisite care, filled with hotel soap squished together and molded into a perfect Milky Way, Butterfinger, or Mounds shape.
I extracted every item, and there was not one morsel of food or drop of actual drink in the entire frij! Even the package of mints on the dresser had been replaced with clothing buttons from the complimentary hotel sewing kit!!!
I stomped down to the front desk with all the evidence, but all the brain-dead, cross-eyed trogladyte calling himself the night manager could do was say he'd leave a note for the general manager to decide whether or not to reverse the over $200 now charged to my credit card for water, sand, and soap.
I got some chips, cookies, and a Coke from a vending machine and called that dinner. I went back to the room and took a shower. No soap--the perfectly folded wrappers had cardboard inside--and, of course, the real soap that was inside the candy bar wrappers were down at the front desk where I'd left them.
