When I travel I normally tip the housekeeping staff by putting $2-3 on the pillows; $5 if I'm with my family and we have more towels/bedding to deal with.

I also routinely take one of the many glasses in the room, put it on my desk or dresser, and empty my pocket change into it every day. At the end of the week, I just pour the glass into my laptop bag to take home and empty; I hate jingly pockets all week.

Anyway, a couple weeks ago I noticed my change cup was empty one night. I thought I'd put some coin in it the day before, but couldn't be 100% sure, so I made a mental note when I tossed a buck or two into it that night... sure enough, the next two days, the change in the cup was disappearing when my room was cleaned.

This is the first time I've ever expereience what I consider any kind of "theft" from my room. I routinely leave laptop computers, digital cameras, jewelry, etc lying around -- I"ve NEVER had an issue. It's not worth making a fuss over a buck or two in change, but I'm curious what other people's experiences were.... have I just been lucky up until now? I've been a road warrior for about 5 years, mostly in the US, and never had a problem, knock wood.
