Yes that drives me crazy.

I worked in fast food before and it never ceases to amaze me the things people complain about.

I am always polite to people working in such industries because I know how frustrating it can be. Just last night we went to KFC and this lady got the wrong thing and she came storming in and was complaining and talking to the kids that were working like they were idiots. The manager came up and asked what the problem was and the lady said she got the wrong thing. The kids were putting together her meal as she was still complaining about it and the manager said "Ok well I can see they are working on getting you a new meal right now" the lady stood there and complained the whole time to everyone in line and on her way out she says "I guess you get what you pay for"..... GRRRRR I always want to ask people like that how they would feel if they made a simple mistake and I came to their work and treated them like they were the idiot in front of everyone. Mistakes happen..... sometimes its frustrating but YOU are not the only person in that restaurant.... a simple explanation of what happened is suffice and they will fix your problem. I don't know about you but yelling at me does NOT make me want to fix your problem faster.
