We bought a tv set recently in one of those huge stores. The salesman completed the sale and gave us the packed tv and brought us to the cash till (we pay in cash). I was asked loads of questions, telephone number, email address, mobile telephone number, was I the main breadwinner (now there's a word we don't hear too much of these days) etc. We spent more time at the cash till than in the process of buying the item. Obviously, we were supplying the outlet with loads of stuff which they use for future sales drives and sales tracking. Great! But not on my time please Rant Over
