This is the most disingenuous charge that hotels try to get away with - it really ticks me off! We all know (hopefully) about the excessive phone charges, but this extra space to pen in an additional tip is outrageous.
The room service food is already highly priced; the $2.00 "delivery" charge added on to the price of room service food is ridiculous (why else would I order room service unless it was delivered???).
And then they leave an empty space for an additional tip to be written in. This obviously confuses and/or intimidates some clients, and I can't help but wonder if this is the intention of hotel management? Why else would this space be on the bill.
I am a good tipper. But I REFUSE to add a tip to this type of room service bill. I politley cross out the line and thank the server.
