"One hole" joke

One day a man was golfing when he forgot what hole he was on.
So he went up to the women in front of him and said "Miss im sorry to bother you but i seem to have forgotten what hole im on could you help me?"
The lady in reply said "yes im on the 5th hole and your one hole behind me so you must be on the 4th."
The man said thanks and went on playing.
Later it happened again so he went to the lady and asked her what hole he was on and she said" Im on the 12 hole and your one hole behind me so you must be on the 11th.
Again the man said thanks and went on playing.
Later after the man had finished golfing he went to the clubhouse to get a beer when he saw the lady sitting at the bar. He went up joined her and started a conversation.
He asked her what she does and she said "im a saleswoman.
Suprised he said i am too
He asked her what he sold and she said if i told you you would only laugh he said no i wont i swear.
so she said "I sell tampons"
with that the man fell to the floor laughing and she said "see i told you you would laugh and he said "Im not laughing because of that Im a toilet paper salesman so Im still one hole behind you."
