Considering how many annoying customers people working in retail and food service run into from day to day, it can be hard for them not to run together in workers' memories.
That's why unless a customer does something particularly weird to stand out, you tend to hear more about bad types of customers than you do specific people.
But of course, sometimes problem guests really do make a bad enough first impression to stand out. And whether that's because they made an impossible request or they were cruel even by the standards of your average entitled jerk, employees can still end up remembering them years later.
And that phenomenon turned out to be bad news for two tourists who thought they could get away with a criminally destructive act.
