Just want to guage opinion on this really as I would avoid getting in the same supermarket checkout queue as someone I know. However, today I had a friend (opposite sex) who queued behind me and I didnt notice until they had unpacked everything and I was mostly finished repacking up my stuff. He even made a joke about looking at my stuff.
It did feel a bit odd actually and made me realise that I would have avoided going behind someone I know in order to give them (and myself) privacy. AIBU?!
