I am always amazed how people speak to other people, especially when I am at the shops and I see the way people treat or speak to sales help/cashiers/food staff. Also in restaurants, they must know they are going to get spit or worse in their food, yet people will go on being jerks to the 'help' as if they are just there for their whipping boys. People will never learn give out what you want to give back. Well, some will, I hope!
