I think it's a great idea!
BUT... be sure that everyone TIPS!!!
When I was in RIT, I noticed a lot of deaf people didn't tip. One time, I was standing in front of Tower A waiting for a friend. I saw the pizza delivery guy approach a deaf guy. When the deaf guy gave the delivery guy cash, he demanded full change back. After the delivery guy left, I asked the deaf guy about it (out of curiosity). His response? "Oh, he forgot to give me my full change." When I asked about tip, he said... "What for? I only ordered the pizza! I don't care about the guy!"
