BORDERS a bar of chocolate

In London,a popular book shop,BORDERS.
Since 1995,I go to England almost every year for holiday and study and work.
London is changing something every year.
In BORDERS,when I buy a book, a shop member will give me a bar of chocolate(the 2nd photo,borders chocolate).
Very very good!!Thanks a lot!

WH Smith ask me as well,Would you like a bar of chocolate? London people comments are...?Maybe this is London.
