How old is this young woman? She sounds like she might need to be a tad bit more assertive. “I’m sorry, you cannot access the soda machine, unless you pay for soda. You ordered water.” Or, “Are y’all all right? Is there anything I can do?”
Having said that, was she alone? It is my opinion that in most situations, businesses, especially at night, should never leave an employee to work alone, in this day and age. Sounds like she’s been kept in a jewel box, and just allowed out to make a little bit of shopping money.
My husband has a granddaughter, who is 19, has never held a job, never gone anywhere without her mother or grandmother, except elementary school, and just got a certificate for a certain job classification (her mother took the class with her), and now, could be making$12-$15/hr, but her mother says she’s afraid to take the bus a couple of miles so she can actually work! Sorry, I know this isn’t germane to the topic.
Too scared to be around black people? Stay home, then, I guess; there’s an awful lot of them out and about.
I see a lot of black brown and yellow people working at Subway. Her coworkers are all white every shift?
That would be a bad idea.
