We might do better to question the insatiable desire to collect as much information as possible about every aspect of every individual's life. Much of the data collected and stored (only to be subsequently lost) seems to me to have more to do with control freakery than actual need to know.
Why do Curry's need to know my name, address, postcode and telephone number when I wish to purchase a set of earphones for my daughter? What are they planning to do with this information? The answer to these two questions, when I asked them last month, were (i) "It's the rules" and (ii) "Dunno ~ it's the rules". My next question "Whose rules?" was met with a shrug. I made the purchase at another store.
