In my local convenience store there is a system of one queue for all the tills. Invariably someone will just walk up to a till where someone has just paid, ignoring the queue and start unpacking their groceries . The staff never say anything.
This evening there was a very long queue and when I came to the top a woman with a basket full of groceries just started hovering near one of the tills ignoring the queue. When it became free I just walked up past her and put my stuff on the belt. She started making an indignant face and glaring at me. I said politely 'there's actually one queue' and she said 'yes but 2 tills' and I said again 'but one queue' to which she reiterated that there were 2 tills.
Why on earth did she think that 7 or 8 people would all be patiently waiting at one till leaving the other one free?
AIBU to think she was just a cheeky chance?
