Yes it was a small run business, but come on 50p and the guy spent half a grand, perspective and common sense and keep customer happy.
50p is nothing when you spending 1000X more than that!
Not sure what the argument here is. Your friend obviously had £23 so why should the guy at the counter go, oh don't worry, no need to break the £20, just give me the 3 coins instead.

It would potentially be different if your friend only had £3, and it was a case of pay £3 or leave the stuff.
