That’s the real issue that people are underpaid. But knowing that why would somebody use the service of somebody they know relies on tips and refuse to tip? If I know I don’t wanna pay tips I’m not going to a bar I’m drinking at home
Tipping is not a requirement. It’s just a social issue where two sides argue and judge each other. It should be at the customers discretion but too many people got it in their heads that it isn’t.
