First off, apologies if anyone has used this opener before and I'm not giving due credit. As far as I know it's original and I wanted to know what you all thought of it. I haven't field-tested this yet. It's meant to be mostly an opener for bars. So I approach and the dialogue goes something like:

"Perhaps you can tell me something about restroom etiquette in bars that I may have missed. Say you’re in the bathroom at a bar and you get out of the stall to wash your hands. But at the sink there are two very drunk people making out, and you tell them to go away but they just don’t listen. How exactly would you get rid of them?" [Imagine lots of mystique and enthusiasm when I say this, obviously...]

It's meant to be an opinion-like routine, but without the formal question, "Can I get your opinion on something?" I wouldn't always feel comfortable asking that in a bar. Anyway what do you think of this? Totally hopeless? Can it be improved somehow? Thanks in advance!

Yeah that's perfectly fine. Go use it and write your results.
