We were in town visiting family and decided to grab a few burgers. We were seated quickly, but sat for a good 15 minutes before someone came to get our drink orders. She did apologize and the restaurant wasn't that busy to excuse the lateness of coming to our table. She asked if we'd been helped and I looked down at our empty table and politely said no.
Most often we get amazing service and the waitress was very nice that night so I can let what happened when we sat down slide.
