Donna in MO

I just wanted to know if there was a professional way of letting clients know that tipping/gratuity is a part of our paycheck. I work in a salon in NC and just moved there from FL. I don’t think people up here are educated on gratuity in a salon..the ratio is like 50% don’t tip. Is there a statement or something with correct verbage that I can use and print up and frame to hang in our Salon? These people need to be educated…I’m making so much less up here because of the lack of people who tip! I feel like moving back to FL! Any info on a statement or tipping policy that I can print up and frame would be appreciated.
