ARCO Gas Stations complaint: rude employee

I am a regular customer at this location I often buy coffee, gas, snacks, cigarettes, lottery. I am currently waiting on EDD to file my extension for UI benefits so while I wait I do delivery jobs instacart, postmates, doordash. Unfortunately with SIP there is no where to use restroom or wash your hands whenever I am here if I need to use the restroom the staff is very friendly except the gentleman with the accent he always refuses to let me use the restroom tonight he told me I would have to wait until the next shift arrives to use the restroom because it has been cleaned. I asked him so I have to wait an hour or more he replied yes. I told him he was rude the only employee that is rude to me. I am providing essential services for our community and it is unacceptable to be treated that way I was getting a coffee the tall gentleman was assisting me I explained how the employee is always rude he replied he is an Assistant Mgr. I explained I have been a manager most of my employment and I would never treat a customer like that. Just unacceptable attitude and rude.
