I was asked to show my ID when I bought a few cans of beers along with the basket full of stuffs on a Sunday afternoon from a BP petrol station. A young man was at the counter and just refused sell me beer without the ID. I think it was probably a case of harassment than anything else, although anyone can be asked to be ID-ed.
Although I had my ID, I refused to show it, left the full basket for him to sort out and went to an off licence a few miles away.
This happened about about 13-15 years ago! I am 60 now! 🤣
