Always a hole behind

A man,while playing on the front nine of a complicated golf course 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 his confusion and asked 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 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 hole ,you are a hole behind me,so you must be on
the 13th hole;
Once again he thanked her and returned to his play.He finished his round and
went to the clubhouse where saw the same 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 that you are in the sales profession.
I'm in sales, also. What do you sell? She replled, If I tell you;ll
laugh.''
No I wont. ''Well. if you must know,she answered.I work for tampax.''
With that ,he laughed so hard he almost lost his breath.
She said See, I knew you would laugh.''
Thats not what I'm laughing at.''he replied.''I'm a salesman for
Preparation H,so I'm still a hole behind you.''
