So this just happened to me. I went to a local bar that just opened up because I heard they have a pretty decent beer selection.
Me: I'll take an Ithaca Flower Power (local IPA)
Bartender: Sure thing
As I wait for my change, a guy walks up next to me and takes a look at the taps. A second bartender shows up and asks him what he wants.
Bartender: What'll ya have?
Guy: Ithaca IPA please
Bartender: We don't have Ithaca IPA
Me (to the Guy): You want the flower power
Guy: No, I don't want that
Me: You said you wanted the Ithaca IPA, that's the Flower Power
Guy: No, I said I want the Ithaca Double IPA
(I'm pretty sure they don't even make a double IPA)
Me: You want the flower power, trust me.
The guy orders an Angry Orchard (hard cider)
I laughed to myself. I guess he thought a good alternative to a double IPA (that does not exist) is a hard cider.
