Oh, and numerous swimming pool incidents. Public swimming pools seem to bring out the worst in some people. Some people get annoyed that others can swim faster than them and take it as a personal slight to be punished, others are just plain creepy, many can't follow the lane directions and cause mayhem, and so on.
One of the worst was recently when I joined the fast lane which contained a reasonably fast front crawl swimmer. Just 1 fast lane and 1 slow lane with several slower swimmers.
Said woman then came up to me before I started to swim to say that she didn't want to follow the anti-clockwise lane directions but wanted us to take a side each.
I declined, it was lunchtime and other swimmers might come in and I also don't train that way and find clockwise lane movement much easier. And the signs at the end of the lanes had instructions and big arrows telling you do that.
(Apparently, it was all because she was the fastest swimmer and might catch up with other swimmers and be delayed.)
She then had a tantrum. I don't take any shit from anyone and tend to remain annoyingly calm and logical and just kept repeating that I wasn't going to do as she wanted and that she was very rude. She was screaming, yelling, shouted racist abuse at me, really nasty stuff designed to upset, and then suddenly swam off in the middle of the lane.
I tried to swim but she was deliberately swimming up the "wrong" side so that she swam into me head first. Very childish behaviour and dangerous at speed.
I complained to the attendant, who "spoke" to her and she stormed off. Ironically, she was a slightly slower swimmer than me. That may have enraged her all the more.
I dressed, on exiting by the pool reception, she was standing there, shooting daggers at me. I was called to the side, as apparently she had made a complaint about me and they wanted to hear my side.
So I was standing talking to the manageress and she was speaking to another employee, she then suddenly decided to leave, had to pass me and shouted at me being an "entitled little brat used to getting her own way". In astonishment, I blurted out that I was a woman in her forties. Without missing a beat she suddenly changed tack and replied "Well you look about seventy". She herself had grey hair and was a fit looking 60 +.
She was absolutely irate. I thought she was going to try and knock me to the floor, despite all the staff now standing there agape, and I remember bracing myself for the inevitable contact. I have never seen anyone so completely worked up over nothing.
Thankfully, she did storm out and I have no idea what happened to her as I have never seen her at that pool again.
Can I also point out that, just as some people might have mental health problems, other people may also have personality disorders which make them behave in the way that they do and the last thing you want to do is to encourage these people by being empathetic or sympathetic to them. The best thing to do is to engage as little as possible and to go grey rock and not give them the reaction they are looking for, which is either getting their own way with no battle or an emotional reaction on your part.
