I wonder if she realised the entire store was laughing at her?

I popped up to our local shop to pick up some crackers and a magazine, and while I was in there I heard this wman SCREAMING. I could hear her over the other side of the store, and when I say 'small' shop I mean slighter bigger than our house.
This shop has a post office attached, and that's where she was. I couldn't hear xactly what she was saying, but I over heard
'EVERY OTHER POST OFFICE DOES IT'
'YOU LITTLE TWAT'
Varoius swearwords
'I'LL BE BACK IN HALF AN HOUR!'

As dhe stormed off (I got a look at her and may I just say, she's the stereotypical inhabitant of the council estate just up the road), the young man said 'Thankyou!' after her, at which point she screamed
'DON'T THANK ME!', which was too much for me and for everyone else in the store, and we all started laughing as she left.

Note to bitches, act badly and we will ALL laugh at you.

I kinda get the feeling that "Thank you!" was short for "Thanks for the warning!" for being 'nice' enough to tell the clerk that she'd be back in half an hour - time enough for the guy to make himself scarce. ("Here comes that bitch again - time for my break...")

As for whether she knew that she was providing entertainment for those present - I doubt it. Most screechers like that are too caught up in their own little soap operas as The Beleaguered Protagonist Oppressed By An Uncaring World (tm) to notice stuff like that.

Don't single out bitches. Make it for everyone.
