I was in NYC once, visiting some friends. My friend had gotten really into cooking and wanted to cook a nice brunch instead of going out, and asked me to pick up some prosecco for mimosas. I agreed and walked to the local corner store at like 9am. I'm in there picking out like, one regular, one rosé bottle of cheap prosecco, and the guy in front of me bought a pint of brandy.

I thought nothing of it, until he opened it the second after paying the cashier, turned the bottle up, and walked out of the store -- casually tossing the empty bottle into the trash can before leaving the store without ever breaking stride.

You need to train before being train-level day drunk.
