What Do You Do If This Happens to You? [POLL]

Whether you think it's tabu to talk about something as natural as going to the bathroom or not, you undoubtedly have experienced this (or will) sometime in your life.  

There is nothing worse than when your in a public restroom doing your business only to find out that there is no toilet paper.  You look around and see nothing.  Now what do you do?

To be honest this was probably more of a problem before cell phones but, since most of us (including myself), bring our phones in, it's nothing more than a quick call.  But who do you call?  I don't think there is some secret underground toilet paper heroes that will come in with what ya need.  So what do you do?
