NOTE: When paying for a tennis class or league, we prefer you pay by: check, credit card, online or with a Money Order. While we like receiving money we prefer to NOT take cash.
       1. We and you should prefer a paper trail of when payments are made.  Sometimes you and the Instructor "forget" when a payment was made by cash
       2. For safety, we do not want our instructors carrying cash with them on the tennis court. For obvious reasons, someone may think they can get some easy cash if they know the Instructor is carrying a  
            large amount of cash on them at the courts.
