Now I know this is not the case for the OP, but I used to bar tend and something like this happened to another bartender. We were at the same bar and he had run out of margarita glasses, so he pulled one out of the drying rack. The glass was still hot, so as soon as he poured his drink it shattered like an explosion.
Anyways to OP, at least it didn't shatter.
