Where are the bathrooms?

As much as people complain about the lack of public restrooms in NYC, I've found the problem much worse in LA. I've been into multiple Starbucks that don't have public bathrooms. Are you joking? No, I'm not. As I type, I'm sitting here at a Starbucks and I have to pee SO badly and I'm screwed! Also, yesterday at Runyon Canyon I thought for sure there'd be some public bathrooms, it's a park right? Nope, no, doesn't matter. The lesson here is: Pee before you leave the house, before you leave the restaurant, and maybe look into catheters if this problem continues...There may be a bladder infection in my future, TMI?
