Out comes a bottle of 1982 Moet Hennesy and a crystal champagne flute. Now this is premium champagne, and with a premium price too. However being the high-roller that you are this is no matter. The bartender pops the cork expertly and pours your drink. You raise the glass to drink,

and it shatters.

why does it shatter?

A) a bullet shot through it
B) some wannabe singer hit a super high C note and destroyed the fine glassware
C) you clumsily drop it
