Good one - as always! :-D
Not a big Starbucks customer, although I have very old but fond memories of caramel cappuccino frappe' ice thingies. Thousands of heavenly calories each.
I don't get the bathroom debate, TBH. When people gotta go, they gotta go.
Why not just let them go? There are stalls and booths for people who would like privacy. If somebody does something creepy, they probably won't last long. Of course, I might be missing something important with my simplistic view. :-)
