The stunningly painful feeling
McDonalds spent years of research looking for a way to trigger. It'll get you as soon as you'
re finished eating and try getting up.
If you have a
long road ahead of you after you get out of
McDonalds, you'd better use the
toilet before you leave, or you'll be painfully holding your diarrhea until you arrive home. Especially if there's blizzard outside, forcing you to slow down, and it's too late to stop anywhere.
