Lost in the hospital trying to find a ward so i asked a man who worked there
me - excuse me do you know which way ward 40 is?
him - you've got the wrong hospital that's not here
me - ..... erm
him - HA! i'm only joking! this way..
Another example on my first day at a new job in a shop. Window cleaner comes in and asks to be paid.
I ask how much?
£25.
I go to ask manager and get another big laugh at how funny a joke he made and it's really £2 
Wtf? It's only ever men that have done this to me and I really can't imagine them doing it to another man. Is it a power thing? It drives me mad!
