What does the speaker do most probably?

Could I have your attention please? Thank you.
   As I told you yesterday morning, this afternoon is our shopping afternoon. If you look on the back page of your tour programme, you’ll see a little map of the city centre, with the names of some of the shops marked. As you won’t have too much time. I’m just going to explain to you what they sell．
   We’re now in the Friendship shopping centre. On your right is Larp’s, a very good place for shoes and boots, rather than gloves, bags, clothes or other. Opposite that is Li-Ning, a good place for sports goods. Not cheap, but really pretty. Next door to Li-Ning is a place for books. They have got books on almost every subject anyone has ever written about, airplanes to animals. but Chinese only—so none of your English books I’m afraid. If you walk along，there are shops which sell cameras, radios, and so on, which you won’t buy. I’m afraid. If you are tired or would like to have a nice cup of afternoon tea, I suggest Splend Tea Shop, where you can have British afternoon tea, with very good home-made cakes, chocolates and other. The shop is two blocks away from here, but within walking distance.
