I didn’t leave but I did get a large group of people kicked out of a Red Lobster once. It was in the 90s when most places still had a smoking area. My wife and I still smoked at that time. This Red Lobster had a huge dining room separate from the rest of the restaurant with a ventilation system of it’s own to remove the smoke. It was a busy Friday night and we waited an hour to be seated. When we were almost finished with our meal a party of 8 were seated at a large table right next to us. We finish our meal and fired up our cigarettes. This rude man in a suit demanded that we put them out because they were bothering him. I told him that he must not realize he has been seated in the smoking area. He just got ruder and told me he is damn well aware where he is sitting and that it was the only table available for a large party unless they wanted to wait and said they had been told the wait was over an hour.
I replied that I was damn well aware of the wait because we just waited over an hour for our table in the smoking area. At this point the bastard starts loudly saying things and getting other people in his party doing the same. They were being loud, rude and launching personal attacks towards my wife and me. The server came over and asked what the problem was. They guy starts indignantly demanding they make us extinguish our smokes. The server told them the same thing I did. Then I told them how the guy had been harassing us since we started smoking. I then asked for the manager. The people wouldn’t relent and were still acting out when the manager got there. He asked them to leave when they wouldn’t let up. He then apologized to us and comped our meals and offered desert. Some people just have no clue.
