WHY do people refuse to say excuse me and then get annoyed with you for not moving...

when you clearly didn’t even know they were trying to get through or past you…? This happens a lot when i am in the supermarket – people seem to have forgotten the words “excuse me???”

I’m not talking about when you can clearly see they need to get through – it’s pure courtesy to move in those instances.

If anyone has any good quips i can blurt out to the offending persons next time this happens i would love to hear them…
