Mixology question

By a happy coincidence, the SOTU and Drinking Liberally both fall on a Tuesday.

So, I thought I'd swing by and, to honor the latest Oration from His Royal Lieness, induce the bartender to make a frothing wingnut for me (recipe by Shystee).

But I have some questions:

1. Is it normal/courteous to hand a bartender a recipe, and ask him to make it?

2. Do most bars routinely stock cans of Cream of Coconut? If they don't, is there a substitute? (It seems to me that asking a bartender to make a special drink might fall within normal bounds, but I don't know about bringing my own ingredients... And besides, if I have to do that, this meme won't propagate, and this is one meme that deserves propagation.

Readers?
