"......noticed it with mostly older Thais"
My (Thai) wife and I pulled up beside the pump at a petrol/gas station a few months ago and while we were waiting for the pump attendant to arrive, a middle aged/elderly Thai lady pulled up on her motor bike in between our car and the pump, and glared at me as if daring me to say something. When the attendant was approaching, she told him how much petrol/gas she needed and once again glared at me again. Now, I'm an even tempered guy and as I'm retired I tend to let people who are in a rush just get on with it - especially when driving! An old pal of mine used to say "I'd rather get there 5 minutes late than not get there at all!"
However, in this instance, a person with a shorter fuse may well have caused a fuss, and I can just see the headline now "Elderly farang causes chaos at petrol station" Sometimes there are 2 sides to the story, but as farangs are "Aliens", the local will always get believed in preference to the farang - especially if there are no witnesses.
And I am not excusing these latest attacks on women by Swiss men - far from it, but just because one of the parties happens to be a woman doesn't necessarily mean that she is the "hard done by" victim!
