just my personal opinion that it's unsavory, but i'm not going to make a face or say something about it because, like you said, it's just the ground. it's more of the action that seems "gross" i guess you could say, because the mouth is so chalk full of germs. but in places like the gym you might be working out near the floor or putting weights on the floor so it's just a no go for me personally
all of my friends, even my mother and grandmother see it as unnecessary and most often times gross. again the amount of germs in a persons mouth is astonishing, and to be spreading that when not necessary just seems rude to most people. (just trying to give the other side of the coin, not trying to pick a fight)
