Alex, I'll give you a CC alternative to a forbidden words list- how about a list of useful phrases for you?
"No thanks, I'm full."
"I'll just have one, thanks."
"Only one drink, thank you."
I'm sure some of the other people here can come up with other helpful phrases.
Alex, I know your initial response will be to thank us for any of our suggested phrases, but no need, as we've seen your picture already and know how difficult it is for a compliment, or indeed anything, to just fall out of your mouth.
