I think you deserve a cookie for actually quoting that properly. Anyhow, this isn't about security it's about shoplifting. When I was a little younger I used to have to check my bag at one certain store. Actually, I love this store but it did cause me to not shop there for awhile. Then I realized there was a way around. Make sure you are wearing your bike helmet (sounds stupid, but this helps.) Then they know why you have your backpack. Second, make a beeline for a shopping basket. This shows that you are actually going to buy things. Last, sneak up behind the security guard and give him the vulcan neck pinch before he gives you any trouble.
