This individual was told he "walked too fast." Why did he not just "walk more slowly?" Was it really that difficult? How come I've managed to get through security so many times without such problems? OK, so I have always been the lowly, scum of the earth passenger, but I've never had a problem despite finding some of the "jobsworth types" you all hate so much.
In any case, I apologise for my rash remark and regret any offensive it may have called the individual concerned, in the event he has read this. I will delete it forthwith to save any further upset.
