Many people believe that  servers give good service for someone that the think will tip well. I find that hard to believe. you never know how wealthy a person is or if they are tight handed with money before they pay. How can you say “oh this guy looks like a big tipper” then work hard for a tip? you never truly know until after you’ve served someone. I’ve worked for a catering hall, and gotten no tips for days at a time. I still gave excellent service, and had an amazing time doing it. Its the customers that make you happy and want to do your job. I met amazing people and heard fantastic stories.
