I'm in the camp of folks that'll go - providing they are healthy - and will bring along half a dozen pairs of those nitrile gloves they sell at home Depot, which we use to pick up the dog's crap every Saturday, to wear while playing the machines.
And no, I'm not saying that I'll be wearing ones that were used to pick up the dog's crap - just the same type as we use for that.
Shake hands, play games, whatever... then toss them out and use fresh ones the next day.
