If in doubt, show it to the server ahead of time and ask..... play dumb, like you really don't know where it is valid. Don't just say, I got this at XXX, but I can use it here!
I've never actually read (or seen) the rules that say it's only valid where it's issued -- I've just never had a problem using them elsewhere. And it makes sense to me that they would work that way.
