Festival Dilemma Girl

I'm at this crowded festival and... oh no, my stomach's acting up! I think it's diarrhoea. What should I do? Here are your options: A) Dash for the nearest porta-potty through the crowd, clenching desperately. B) Try to find a hidden spot behind a food truck, hoping nobody notices. C) Stay put and pray you can hold it, despite the intense cramping.
