Is it acceptable to hold someone’s place in a queue if only one person swaps in?

I was in a long queue recently and someone a few places ahead seemed to be holding a spot for another person who arrived later.

It wasn’t a group pushing in. From what I could tell, one person waited, then swapped out when the other person arrived.

It made me wonder what people generally think is acceptable in the UK.

Would you be okay with it if:
it was one person swapping for one person?
the person had popped to the toilet or to get food?
they were running a few minutes late?
they couldn’t comfortably stand in a long queue?

Or is holding a place always bad queue etiquette?
