Is this fair?

Today we popped into Cambridge. I normally hate going shopping but needs must sometimes.  We were browsing around Marks & Spencer and I saw some trousers I liked. Flicking through the sizes I saw they had no long lengths in any size, just short and regular, which I thought was a bit odd.  Checked a few other styles, same thing, so I went and enquired at the desk to see if they had changed their leg lengths, to be told that they hardly ever get any long lengths for the stores as they are mainly reserved for buying online!!?  What rubbish, do they want everyone to buy on-line thus killing the High Street? Is this discrimination against people with long legs?  Should I send a letter of complaint, or am I wasting my time? I was so cross I was nearly beside myself, took a coffee and a muffin in Cafe Nero before I calmed down.

The upside of the morning was that I did get some really nice short boots in the Clarks shop with 50% off, and some new underwear with some gift vouchers I had for christmas, so all was not lost, but I'm still feeling pretty cross!
