CVS review: Bathroom usage

I walked into this store location to use the bathroom and the Manager, Joseph told me that the bathroom was out of order because he was tired of customers abusing the usage. I told Joseph that it was an emergency and nearly urinated on myself. He told me he was sorry, but he didn't know what to tell me. I said: what do you and your employees do for bathroom usage? This is absurd and totally unacceptable. This place of business should never have bathrooms unavailable because of the amount of employees that work there; customers come into the place to purchase meds from the pharmacy; and sometimes people just have emergencies due to a medical condition. Something must be done about this issue immediately.
