Last night I ate out solo for dinner. When the waiter brought the dessert he also placed the bill holder on the table, then left again to get my coffee.
When he came back several minutes later with the coffee he lifted up the cover of the bill holder, presumably to see if I had put money or a credit card inside (I had done neither--I was going to do that when I was all done and ready to go). When he saw that I hadn't put anything in the bill holder he slowly lowered the cover again and left.
The checking of the bill holder felt a bit awkward. Maybe I should have put the money in as soon as he left it on the table and went away to get the coffee? Is that what people usually do? Or was HE the weird one in this case? (LOL).
