Social conventions say it is very rude and offensive to fail to recognise someone
I've never seen that, but if certain people get upset about that, then they're ignoring the reality that the human brain often forgets things. They aren't special, and there's no particular reason that you'd remember their name. I think that social convention, if it exists anywhere, is absolute garbage and should be ignored outright.
