I treat them well so they play again
Funny you should say that.
When i was 16 or 17 I played pretty good straight pool.
Every wednesday night for quite awhile a family man named Harry would play me straight pool and he rarely won a game.
The old man that owned the room told me that Harry was my customer and to make him feel welcome.
Buy him a soda and a snack once in awhile.
Ask him about his family and get to know him.
Funnest part was that after awhile he asked me what i did for a living and i said I'm working right now playing you.
Then he offered me a day job working for him for what at that time was great money.
I took the job.
But i continued to play pool with him on wednesday nights,except now I didn't have to win to eat the next day.
