Well, no they didn't apologize. I didn't expect them because of the situation. I was literally walking quickly through a crowd of people. They only had a very small window to talk before I was already moving away with my wife in hand. By the time I noticed and stopped and asked my wife, the good samaritan was far enough away in a crowded bar that she wouldn't be able to say anything.
Maybe I don't take offense because she didn't treat me like a suspected harasser. She didn't treat me like anything. She looked out for my wife. I greatly appreciate that she was looking out for customers that drank too much. That was the end of my thoughts.
Why should I be offended that the club was trying to make sure their customers were safe? I guess I would be offended if they stopped me and separated us and asked 20 questions, but that isn't the case. The interaction took maybe 5 seconds and I didn't noticed until I was pulling on her arm and had some resistance. I looked back and by that time she was pulling herself toward me.
