If protesters step up their disobedience, that might include disrupting you when you try to buy gas. Oh, that's not a good idea. Me, for instance, I am SO CLUMSY. What if I accidentally splashed gasoline all over the protestor who was getting in my way?
Gee, if you're so nervous that you sprayed gasoline on them, maybe you need a cigarette to calm down ( or look like you're looking for a lighter).
