Yikes! That even tops the fingernails in my opinion. I am very easy going about things like this and wouldn't mind someone cutting his nails that much (as long as the nails end up in a neat napkin or something rather than on the floor or seats :shock

but s+*t belongs into a toilet, that's what this facility is there for.
I was on a KLM flight to Sydney once (yes, back in the days!) when an Indian lady decided to change her baby's nappy right when the food started to get served. When the steward politely asked her to go to the bathroom, she got cranky, picked up the baby and walked down the entire aisle (in Y) with the stinky diaper open for everyone to smell. We happened to fly right across India at that very time and a few angry faces around had the same evil thought of sending her home the fast way :evil:
