if you are mad, then don't launch there
some people like a little rudeness occasionally, like the Seinfeld episode of the Soup Nazi, there was a drive thru coffee shop in Monroe they called the lady the coffee Nazi. Lady was rude as could be, but there was always a long line to get here coffee. You better not try and make any substitutions or ask for something not on the menu or she would give you an earful
Despite all this, people would go here to get a little dose of 'rude' in the mornings before they went to work.
