We just had an unpleasant experience tonight. Went to a fairly new Italian restaurant for dinner, will post about food later in dinner thread. The check was brought to the table and our waiter didn't even give me a chance to look over it, just stood over us with one of those handheld point of sale devices. I absolutely HATE having somebody stand over me/lurk regardless of what I'm doing. The check also had the QRC code to pay, which I chose to do. I felt very rushed and pressured, but went ahead to add the tip and pay. As I was finishing payment, the waiter walked away to get Craig's takeout dessert. Then, as I jotted down the amount of the tip on the bill, I noticed a 20% service charge had been added to our bill for the 2 of us. The service charge plus tip was about 45% of our food bill. Waiter came back and I guess my face showed my unhappiness as he asked if something was wrong. I spoke about the service charge and that I hadn't noticed it. He said he hadn't noticed it and that they would void the transaction, which they did. I redid the payment with him standing over me again.
Where I live, service charges are required to be prominently posted on or next to the entrance or listed on the menu. There was nothing anywhere, not even for large parties much less for 2.
Perhaps I'm being very cynical, but given that I was being rushed, plus the fact that we are older, I have trouble walking, and there is nothing posted about a service charge, I have to wonder if this was, in fact, a mistake.
I made sure I brought home the voided transaction receipt to ensure against any more "mistakes."
