Most of the time, I have no problem with a sloppy toss of chips being counted quickly by anyone at the table because it speeds the game up. But the rule of thumb for me is that the more it becomes "serious" poker, the less likely I am to announce a number of any kind. If it's head's up and someone shoves out a buy-in's worth of chips, we all shut up.
This pretty much sums up my feelings. As a player, I avoid touching other players' chips. As a host, I encourage my guests to act the same way.
Often in this situation, a player will ask "How much?" and get multiple answers, and I generally let it slide. But when a hand starts to get serious, people usually shut up. If they don't, I'll gently remind them to do so and to let the host or the dealer manage the hand.
