Where do they most likely work?

W: We are short of staff today. Why don’t you call up some of the part-time workers and see if they can work today? We are expecting a massive crowd to swarm us tonight since a great review got printed in today’s local paper.
M: Is that why we are getting so many calls? I couldn’t figure out why the phone was ringing off the hook.
W: I didn’t know about it either, but one of the customers told me that he came after reading the review.(57)He also complimented us on the great food we serve here.(56)
M: That’s good to hear. All the renovation work we did here and hiring the new chef we scouted from France are really paying off.(58)
