Maybe you should hold on to the remote or whatever and say "what's the magic word??" next time lol. Works with small children!
Glitter - you make a fair point and I understand it but in my book there's no excuse for being rude like that. I hate dialysis, I don't want to be there, but that's no reason to take it out on the staff who, while it is their job, they are there to help me get the best treatment possible... yelling at them or being a rude *#)@*#@ won't make it any better for me. I am always most careful to say please, and thank you and be polite - even to the ones I don't really like (there's not many, most of my staff are lovely and it's easy to be friendly with them - plus I bribe 'em with peppermints & chocolate ).
I did say she might just be a rude bitch....but like I tell my daughters, you never know what people are going through in thier lives, you just can't always assume why someone is a miserable person.
