> Using just '12' also signals that fractional units of that currency are not something that establishment deals with (which is fine for Japanese Yen or South Korean Won, but comes across as rude for Euro, and most Dollars and Pounds). Pedantic note: you will routinely see prices specified as “12” on menus in coffeeshops and restaurants in Korea, and it would mean 12000 won. I personally treat it as just one of the tactics a place employs to set expectations and attract/repel audience according to its preferred vibe.
