Where most likely does the speaker work?

Hi, Ms. Owens. This is Stan calling from Mitchell’s Carpet Center. Last week you had ordered a roll of green stain-protected Lomax carpet, and we had told you it would be shipped from the company’s warehouse to our store by this afternoon. Well, we did get the carpet this morning but there was a delivery mistake and the wrong color carpet was sent out. We’ve contacted the distributor, and they say the correct item will be re-delivered by tomorrow. Fortunately, we can have one of our technicians install the carpet in your home this Thursday, the 19th. Please give us a call back just to let us know that this date will be OK with you. Thanks a lot.
