In the West a case is 12 beers (bottles or cans). In Ontario and out East a case is 24 beers (bottle or cans).
Person 1: I got a case of beer, eh.
Person 2: What a bonus! When you said 'case' I forgot that you are from Halifax. Your East coast hospitality is appreciated.
Person 1: It's a hoppy ale, kind of bitter, I hope that's OK.
Person 2: Sounds good to me. The mere fact that it's not 'lite' beer assures me that you are worthy to drink with. People who drink 'lite' beer should be shot and pissed on.
Person 1: Fuckin' rights, eh. Bottom line is there's 24 of 'em.
