I don't have that many things that absolutely gross me out either really. I work in security in the airport so I see plenty of nasty people/bags and stuff in their bags. It takes a lot to get me really grossed out. You wouldn't believe all of the things people carry onto a plane with them. The worst thing is you have to keep a straight face because they are standing right there.
people that drive just below the speed limit in the fast lane of the interstate. I want to bump draft them out of the way in my F250.
You could think of government workers like teenagers. You pay them an allowance, but do you get any work out them? They eat the food, put their feet on the furniture and complain loudly whenever they are unhappy.
