When hiring for the restaurant i was in charge of, 9/10 times the kids didn't have a resume. It's a starting job with almost no experience needed. First job, college cash, spending money, i was more surprised when they did bring one. I assumed it was part of the normal gag, she thought she was a customer based on how she was dressed.
From the manager though, for a quick interview you don't really need a resume, you're looking for quick answers that might pertain to what you're looking for. Availability, transportation, past experience. takes 5 minutes max to see if you want them to come back for a more detailed interview. you'd bring resume then.
