@Branka-and-Silvia0Thanks, I get what you're saying. I do think the situation here is quite different, though. As a nation, we've repeatedly rejected the government's (and EU's) attempts to introduce ID cards and the need to carry them.
Which means, nobody carries them! We rarely have to produce evidence of who we are. In fact, when we vote in elections, we don't even have to prove who we are. Hence the saying here, 'Vote early, vote often'!
If ABB asks for ID, I think guests will provide it. If I ask, I don't think they will, they'll just go somewhere else. Which might reduce my stress but would also reduce my income (by, I think, quite a lot). Tough decision!
