My only experience there was one time and when I got the bill, it was for me and for the table of four behind me. I, of course, called the waitress over and asked what happened since I was alone at the next table. Her answer was many shades of wrong. First she said that she thought I was with them (even though my back was to them). When I asked her what made her decide that I should get the bill and not them. Her reply was... "Well, I saw you get up and ask them to give you the ketchup from that table. I then asked why she then though that I was sitting alone I was the one that was going to pay. Her reply was... "they were all women and I just thought they were with them then you when you asked them for the ketchup I assumed you knew them". I then said that was quite a stretch and the only reason why I asked them for the Ketchup was because you didn't make sure I had some on my table".
I wasn't really mad, just wasn't really able to wrap my head around the whole thing. She corrected it and we all lived happily ever after, however, I never have been back again. Plus I saw the entire loop of old movies at least three to four times before I even got my order. I didn't report it, because the way she handled everything I also made an assumption that she was new and hopefully she never made that mistake again.
