I just stumbled onto this thread. Great thread!
I only play part-time. Anyway there was this one time I was playing poker (live) and I get a phone call from some acquaintance. I don't know her very well, she is a friend of a friend. She's asking me for some stupid stuff that I was finding out for her, I think it was where she should buy a sweater or something. Then she says "Oh sorry is this a good time to talk?" when she was already talking for a minute or so
I say to her, "I'm playing poker at the moment, do you mind if I call you back tomorrow?" And she is like, "Are you gambling?! Gambling is wrong! You'll lose your money!" I said, "Are you stupid? Bye." Then I hung up
I think in general this is the correct way to approach awkward situations.
