I'm going to loudly announce that a customer's credit card was declined after he ran me ragged while serving him and his date and posse
Why would embarrass him?
I don't really care people have done this to me all my life.
Please don't be childish. You shouldn't lose your composure about trivial things. It is awful for the server.
Ignorance seems to be bliss, I'm sick and tired of being told not to be a brute.
It can be really hurtful to put people on the spot like that. I mean you don't even know that the card will be declined. Are you planning on doing this on purpose?
