Reacted with all the class and dignity I have come to know from you Lorelle my firend well done!
WHy is it that 'older people' seem to think manners are only for use by younger people? Respect is earned not demanded. Nasty cow she sounds. You technically have yourself an assault there (you were walking away) but the chances of it going anywhere are pretty much nothing. Sorry mate.
I agree with the others though. How does that woman know that you didn't pay for her?

Hope C had a lovely day anyway.
