Standing at a busy bar, I told the bar man the lady next to me was next in the 'queue' because she was standing there before me. She replied, with a face that's been slapped with a wet face, 'err, I'm already being served'
AIBU to expect a thank you, or at least a small smile??
I didn't do it for gratitude, I did it because I was brought up with manners, but I think a thank you would have been polite?
