Why some people say do you have a bathroom? or where's the bathroom? instead of saying do you have a restroom? or where's the restroom? A restroom is not a bathroom. How many here ever take a bath in a restroom? Why do some people say do you have a bathroom/restroom? No, I say, I just crap in a bucket in the back yard. Of course I have one.
Or when people say or ask you got haircut. I am tempted to say Oh, Shit! Is it bleeding? and Oh, damn it! Which one?
