Attempting to publicly humiliate a customer rather than hold the server responsible for a tip, which is so obviously chosen to send a message, is simply to confirm that the owner of the establishment shares the entitlement mentality of the server. This might explain why bad service goes unpunished in this establishment.
I wonder what other customer behaviors might merit public shaming by this owner? Sloshing one's coffee into the saucer? Spilling salt on the table. Asking for a second napkin? Perhaps the owner should post his public shaming policy so that customers are forewarned that they might face more than just bad food or bad service.
Mister McCoy should, if he is able, post several receipts which show him tipping generously ...Black people don’t tip well, period, so i would doubt he is able.
