It's well known in the restaurant business that minorities are notoriously bad tippers, even NO-tippers while also being some of the most demanding and downright rude patrons. My family has been in the restaurant business for 50 yrs and have experienced it many, many times over the years. It's really weird, it makes you wonder where they learned not to tip from and why?
A policy like this eliminates that problem and should be welcomed by all servers. Other restaurants should adopt this great policy.
According the the pro-tipping crowd, minorities must really be treated like scum when they need to eat outside of the home.
Which has led many a waiter throughout the years to say, "Dangit, I just got stuck with a bunch of Canadians at my table."
At my last job I ate out 10-15 nights per month. I learned to tell which tables would be asking for freebies at the end of their meals.
Since I dined alone, I always listened around me. Sure enough, after the meals had been eaten, the complaints would start rolling in and concessions would be made to those I noted when I was sat. Predictable, I tell you.
