If I drop a fry on the floor in McDonalds bathroom...is there EVER a reason to pick it up and eat it?

OMG DONT EAT IT, unless you don't have a problem with licking the floor, because eating the fry is like licking the floor. That's how people get sick. Even worse, anything could be on the floor, like somebody's piss, and you don't want to lick that, you would get sick. I don't want you do contract a disease, so please, do not eat the fry!

I don't think it's a good idea to eat it in that manner because the floor is filled with germs.

Yes. When it lands in your happy meal box thats on the floor.

Or you can lay down a strand of toilet tissue and drop it on there?

No you have no idea what goes on in public bathrooms trust I would not do that

Hell no! The amount of chicken nugget **** bacteria that is on that floor is crazy.
