I thought exactly the same... I might take some photos of my local PC World to give a direct comparison to the UK "PC superstore" !!!
Most are in their 30's to 40's. A lot just come in for memory. I do about 3 to 5 full builds a day. CPU, Mobo, Video card, HD, SSD, DVD, etc. I should really take pics of my actual store. My first day there, I applied.
