I recently moved to Pittsburgh for school and I wanted to enjoy a night after an exam with my classmates. Unfortunately the service here was very terrible and ruined our night. I was tolerant until the waitress came to me while I was playing ping pong and questioned the amount I tipped her. She had a very negative attitude about it and that is NOT how you talk to a customer even if you feel like the tip was unsatisfactory. The tip I gave her is standard where I come from for a student without income. So it was a learning experience for me to learn what's standard in Pittsburgh. However, that doesn't mean she needs to talk to any customer the way she talked to me today.
