On my first trip to the US I walked into the first 7/11 I saw and ask the bloke for "20 Fags please"But seriously, traveling to a foreign nation can be fraught with peril.
(a fag is English jargon for a cigarette)
You didn't ask for a brand name? Most people would. They would say 20 Bensons, 20 Marlborough, etc. You are trying to crack a funny, but you couldn't be any less funny and look rather ridiculous after that fake statement.
Agree! Also 20 packs of cigarette would be too much. Even a carton only contains 12 packs.
