Yes, I'm a big finger locker when it comes to food. I'll lick my fingers in public too! I don't care. I'm shocked so many people don't like finger licking.
I am fine with licking a finger to sort money out if I need to, I really couldn't care less. I also don't mind doing it if I have to do with any type of paper. Though, I would not do it if I had to hand something to some one else.
Even toe licking doesn't bother me, lol. I don't lick my toes but I could do it. Though, I have have this loose skin around my big toe and teeth help with picking that skin away.. Fingers just don't do it!
Ya, I know, gross.. But it doesn't bother me!
