No problem. :)
The only trick with Starbucks is to make sure they will schedule you for at least 20 hours a week. Honestly, if you have any clerical or technical skills, I would go for temping. It pays more and is (in my opinion) more interesting and fulfilling (and yes, I've worked at Starbucks).
Speaking of Starbucks, they are a good bet for public bathrooms. They don't seem to care if you're a customer or not, they're single stall, and they're everywhere. Also, Au Bon Pain, fast food places, and the mall are options. *Some* T stops have bathrooms, but they are pretty nasty (like worse than gas stations). It's basically the same game of learning which shops/restaurants have public bathrooms and which don't. Is it different in Columbus?
