Black Walnut Cafe Manager interview questions

Applied online and an outside recruiter called me. Did a phone interview and was set up for a guest visit. The guest visit was in a store that just opened and after a brief interview I was told to float around and Eventually do table visits?!?! I personally wouldn't want some random person talking to guests but I did it and bussed tables too. Lol. Not a very professional way to conduct a guest visit. But they got some free labor from me without offering me the job.
