"Sales Man" joke

A man went to a strange town to be the guest speaker at a business meeting.
When he arrived at his Motel, he found he had a lot of time before the
meeting so he got the directions for a nearby golf course from the clerk.
While playing on the front nine, he thought over his impending speech and
became confused as to where he was on the course. Looking around, he saw a
lady playing ahead of him. He walked up to her, explained the situation and
asked her if she knew what hole he was playing. She replied "I'm on the 7th
hole and you are a hole behind me, so you must be on the 6th hole".
He thanked her and went back to his golf.
On the back nine the same thing happened and he approached her again with
the same request. She said "I'm on the 14th, you are a hole behind me, so you
must be on the 13th". Once again he thanked her and returned to his play.
He finished his round and went into the club house where he saw the lady
sitting at the end of the bar. He asked the bartender if he knew the lady. The
bartender said that she was a sales lady and played the course often.
He approached her and said, "Let me buy you a drink in appreciation for your
help. I understand you are in the sales profession. I'm in sales also. What
do you sell?"
She replied, "If I told you, you would only laugh."
"No I wouldn't."
"Well if you must know", she answered, "I sell Tampax."
With that, he laughed so hard he almost lost his breath.
She said "See I knew you would laugh."
"That's not what I'm laughing at" he replied, "I'm a toilet paper
salesman, so I'm still a hole behind you!"
