The wait person is a recent immigrant. Send them to sensitivity training to learn not to use racist language. We used to do that in the Army years ago. If the soldier didn’t adapt then they were given a 30 day out discharge.
Wouldn’t it be great if ALL “immigrants” were so instructed? (and it wouldn’t hurt if more than a few Americans were also instructed; now that profanity is used even on news broadcasts, it appears anything goes.)
