One clap ? I always say - I'd hate to go drinking with them - if they can't even share a clap - what would they be like if they had to pay for them LOL. BUT, I know there are one-clappers - the ones I don't understand are the normally high clappers who on occasion give you one clap - that's the one that makes me think - say what????. But I just treat each clapper the same whether one or fifty. 😎™
