W: I wonder if you can help me. I’ve been so busy sightseeing these days and I haven’t had time to do any shopping. And now it’s almost end of my tour and I’m leaving tomorrow. I need to buy and take presents for my family members.
    M: I’m glad to be any help, although I’m new at this job I’m afraid. I’m American and I’ve been working with the travel agency for 3 months.
    W: Well, I must buy a warm jumper for my mother so that she can wear it in winter back at home. My sister likes perfume but not expensive ones. And then some wine and after shave for my brother.
    M: Can we stop for a moment and I’ll tell you where you can get some of those things. Have you got your map there? Well there’s Scorch Wale shop here on the left hand side as you go down Region Street from the hotel you are staying at. They have all kinds of jumpers and skirts and…
    W: Oh, but I want it for myself. I love those skirts. Do they sell socks too? You know, socks for a woman, I mean.
    M: I’m not sure, there is a sock shop on the opposite side of the road, in fact. Now, as for your perfume.
    W: No. I’ve changed my mind. I think, a book for my sister and a record for my brother. Can I get those there too?
    M: There is a big record shop in the Circus itself. You’d find good selection of books at Hacher’s. That’s a little away along the Piccadilly Street not the Circus. On south side, that is, about there on the map.
    W: Ah, I see. Well, that’s about everything then. What a lot of shopping. After that, we’ll need a nice cup of English tea.
    M: I can tell you where you can go for that. If you go along the Piccadilly, pass Harcher’s, you will find a very good tea shops called Reshow on the same side of the street. Funny that one of the best tea shops in London has a French name.
