Where do they most likely work?

W: Mark, did you get a chance to work on the display stand by the main entrance?
M: I’m sorry, Ms. Channings, but I’ve been busy sorting out the shipment of shirts and jackets that came in this morning.(44)I am still going to need another hour or so to finish things up in the storage room. I will get to the stand after I come back from lunch.
W: In that case, go right ahead, and finish up in there. I’ll have Linda get started on the stand.
M: Oh, I sent Linda to pick up something from the first floor security office.(45)Why don’t you ask Paula to do that? (46)She is the one who dressed up the mannequins last week. She did a real good job on them.
