The experience my friends and I had at the popular Outback Steakhouse restaurant was an unusual and memorable one. Encounters such as this one can easily be misconstrued especially since the bartender was white and the customers were black. But one thing for certain, it illustrated how poor customer service can leave an aftertaste that will cause anyone to avoid patronizing at an establishment for years to come.
You have a long relationship with this customer and it is exactly at this time they need to know that you're genuinely upset with whatever has developed. You need to take a breath before you engage with customer or staff. You also need to understand that giving up completely to whatever demands are made and make the situation go away is not always necessary.
