Material Chaos

You would think that in this material world of ours, retailers would make it as easy as possible for people to buy things. Apparently not. The latest trend is to make it as difficult as possible for people to buy things.
On returning home from a weekend in London, Mrs Journeyman and I stopped in at Lakeside. (It was pouring with rain and that was the only place we could think of to walk a bit without getting wet). On passing through House of Fraser (as you have to do to get from the covered car-park) we noticed a display of the latest (and last) Michael Jackson DVD. Our daughter is music-mad and had a birthday coming up the next weekend so Mrs Journeyman went to buy a copy.
First she had to swear an oath that she was over 21 and then give her name and address (? so they could come chasing after her if she had committed perjury).
What is that all about? We are talking about a DVD, not alcohol or drugs, and a PG rated DVD at that. This is advisory guidance that it may not be suitable for children under 12. It is not mandatory - but even if it was, where does the 21 come in? Although Mrs Journeyman looks young for her age, it is quite obvious that she is over 21 and well over 12. And why do they want her address?? To pass on to "Big Brother" who keeps a list of anyone purchasing a Michael Jackson DVD in case they might be seditious agitators?
On questionning the sales girl, she admitted that she thought this was completely over the top but, after having gone to check with the manager, returned to tell us that this was now "policy".
Once more I have to ask the question I am renowned for ...... Why? Luckily, at the time we were the only customers at that counter but in the run up to Christmas this "policy" is going to cause absolute mayhem ....... and for what benefit? Perhaps, if any senior management from the House of Fraser are reading this, they would care to enlighten me.
