We are a small operation with only one person working at a time. So we put a lot of trust in someone when we leave our business. We never hire a stranger off the street. Most often a new hire is a customer or a friend of our family. My son's are in their 20's and they have lots of friends. We always pick someone that we have known and interacted with for quite some time. My husband says "you can tell alot about a person by the way he/she plays pool". For example do they cheat, play on air, act a fool etc. or do they appear to have ethics, play like a gentleman, interact well with people and pay their debts. You really can tell alot about a person on the pooltable. I have many people ask for a job in my poolroom, and many times I hire someone other than the person asking because they aren't what I'm looking for. I also like to hire college kids, they seem to be a little sharper...
Good luck in your search.
