I was actually asked to stand still and stop dancing during the Fado section at one of my London shows in 2020. This English woman behind thought I was gonna follow her instruction, I turned around, looked at her straight in the eye for 5 seconds and said nothing. I continued dancing all along. Didn't give 2 craps about it.
When I got to see Depeche Mode front row this fat lady asked me to move somewhere else because her friend was waiting for her... I just told her it wasn't my fault she didn't get to the venue earlier or couldn't run any faster and ignored her during the whole concert Later that evening, a young guy asked me to stop using my phone to take pictures or record videos, I turned around and asked him "Will you stop fucking with me?". He didn't say a thing.
I don't know. People at concerts behave in different ways, and I have learnt that when they detect you're attending on your own they believe they can get away with anything. I'm a teacher you know and will never tolerate other's crap behaviour.
