Where's all the Toilet Paper?

In many bathrooms in Colombia, including many at La Javeriana, instead of having a toilet paper dispenser in every stall, there is just one dispenser on the wall by the sinks, and you have to grab enough toilet paper you will need before you go into the stall, otherwise you will be caught empty-handed with your pants down (literally). It's a good idea to figure out the location of the toilet paper dispenser(s) before you go do your business.

I learned this the hard way.
