One of the brewpubs in the company that I work for complains of a "Big group of Jehovah('s) Witnesses that come in every Tuesday night and act like complete asses." Just a few of the complaints are:
No gratuity-ever.
They are needy and rude with all of their servers.
Their kids are loud and obnoxious, leave huge messes behind, and disturb everyone else in the establishment.(Minors are not allowed after 10:00 pm. They argue that they came in before 10 and therefore should not have to remove their children.)
They constantly argue about their bill and often refuse to pay for items that they claim were never ordered or were somehow "unsatisfactory".
The list goes on and on.
The sad part is that it is against policy to deny service to people who are rude. We have to have a pretty serious offense to "86" an individual, to "86" an entire group is unheard of.
Maybe they need a "Special Talk" about how to behave in public.
