Unanswered is the question, does the hotel have a rule about having to shower before getting in the pool? Did the man observe they did not follow it?
The BS about the Starbuck's bathroom is just that. They can't have people taking up space in the place and not ordering anything. Starbucks had a rule that you had to be a patron to use the bathroom, Starbucks a had right to enforce that rule. Starbuck's "victims" settle for 1$.
