I was going to grab a quick drink partway through a long walk. I decided to pop in to the bathroom before ordering. Big mistake! The woman at the counter literally chased me down and stopped me, informing me it was for paying customers only. I understand why restaurants have that policy, and I was willing to shell out for a beverage for the "privilege" of using their bathroom, but she was SO rude and aggressive in her approach that I changed my mind. When I tried to explain to her why she had lost me as a customer, she replied "I'm not your government," I guess she was implying that you should only be allowed to use government subsidized toilets if you are in a position where going to the bathroom is a higher priority than adding thirty cents profit to some awful woman's bottom line.
There are so many other places to eat in the area that would be grateful to have your business. Go there instead.
