>>12528797>sidestepping questionwhen I hit up my dealer, "let's meet at 5 or 6 on X day" is confusing, when you add am or pm then there's no excuse to be late-because that's assuming you know how to read a clock.
and nobody says "let's meet at 17" or "let's meet at 17h", so far I noticed that only French people do this, but then for an english person, they'd have to make the extra effort to do 17-12=5 which can lead to mistakes for someone who's in a hurry.
