How do you deal with unpleasant people that you come across? List as many answers as you wish.
My answer is:
I would calmly ask them to repeat the abuse that they just said. If they repeat it in a more normal manner I'd say. "Oh, I thought I heard you say something else." If it is just repeated, I would say "I'm not paid to listen to that." and ignore them.
Now it's over to you....
