So I went to a booksigning event the other day that was held at a restaurant. I was told the cost would be $15 for some hors d'eurves and that I had to reserve a seat with my credit card.
Upon arriving, they rung me up and handed me a bill of $16.24 and I had to sign and put my total (there was a tip line.) I didn't even think about it (because it sort of felt like carry out the way I was signing the bill at the counter) and just put a line in the tip line and made the total $16.24
The manager kind of gave me a dirty look and then I realized "Oooh...I didn't tip." It was too late then and so I just walked away feeling partially guilty. But, I also thought it was just an even $15 event cost, not a taxable and tippable $15. I had also just spent $37 on her book so I was less inclined to feel bad. Plus, I hadn't even been served yet! And, to make me feel less guilty, I wasn't even served all of the hors d'eurves!
Was I in the wrong?
