What does the speaker do most probably?

As I told you this morning, this afternoon is our shopping afternoon. If you have a look at 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 others. 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 others. The shop is two blocks away from here, but within walking distance.
