I agree with the others, go in there!
Interesting because I noticed the time I was there that the busers were girls. I agree that it's a big plus to go in person as opposed to texting or calling
I may be an old folk, but when looking for employment, nothing shows more initiative, ability, and confidence than going there and asking them in person if you can. They use to call them bus boys in my day. Maybe they are called serving assistants now or bus person. It was my first job as a teenager.
You should call them and ask .
