I've often wondered why staff cannot assist during browsing time. For example, in the supermarkets, you cannot get anything from the deli counter. I thought the definition of trade was buying and/or selling or an exchange of goods. Surely if a staff member were to give me advice or hand me an item to place in my basket until the tills opened, that's not trading because no exchange has taken place??? I've searched some websites and I cannot find anything which would indicate that staff cannot assist during browsing time.........all seems a bit strange to me. Why is this Dot? Is it actually Law or just large supermarkets/department stores erring on the side of caution?
