I was going to ask something similar.
I have 3 sessions under my belt. Three different GMs, all three have had hygiene issues.
The last GM was so bad I had to leave the event. When your hair looks like it hasn't seen shampoo in 2015; being forced to watch a grown adult eat Cheetos until their fingers are orange, licking them and wiping the resulting goo on their shirt caused a bit of vurpage; the crowning was smelling like the gym bag left in the locker room for the past month.
