I did not wish to have anything happen to her regarding her job but she just needs to learn better customer service.
I think that was the right thing to do minimus as we dont really know the circumstances behind what caused them to behave that way.
My D.i.Law who works in pharmacy tells me what crap they have to put up with customers sometimes that just makes their day turn to shit and they are still expected to be nice and polite to every customer , they are only human too you know .
Having said that ,I do know there are just some people not suitable to be dealing with the public as they have no people skills at all.
Well done my friend.
