My experience: Well, here's one. At my mother-in-laws wedding reception - At this point I was an active jw, but with a severe attitude. All of my wife's relatives were there. None of them were witnesses. One had dreadlocks halfway down his back; several of them were covered in tattoos, most of them were smoking. All of them were nice people to hang out with. The wedding was dry, so we bought a bottle of rum and kept it in my truck. We would get a glass of coke and then take it to the car to spike. I made a point to stand with this group and hand out with them. Nobody from our congregation came over to introduce themselves, but I got plenty of nasty looks. One elder followed us when we went to the car to spike our drinks.
Two elders together made sarcastic comments about my dress (I had stripped my dress shirt and tie down to my t-shirt) and about our "drinks" to me for everyone to hear, including all of my wife's relatives that I was hanging out with. There was only three people who came over and acted like the entire group deserved to be treated with some respect, and I am still friends with all three of them. That wedding was the beginning of my fade, and it was also the beginning of my bad name with the elders in my old hall.
