Am here at 6:30 monFeb 3rd 2020.They began to ask as to leave in 20 minutes ahead of usual closing time.By 7 we are all leaving,i request to use the bathroom and the gentleman one of the workers vehemently refuses me.

I don't understand your question, however, the staff needs time to clean up/sanitize all the surfaces in preparation for the next day. while I can understand your frustration with the bathroom, you say you were there at 6:30 and left at 7, only to ask for the bathroom at 7 (you were there for 30 minutes). it had probably already been cleaned, and they had already given you a time warning, so this one's on you, chief

What does it hurt to let a customer use the bathroom. I certainly would if it was my business.
