Dude, how can they know what's in your mind?????? That makes no sense! By the way, someone who feels as though they are being disrespected easily and someone who gets offended easily are exactly the same. There's no difference at all.
So, OK, what's YOUR solution? Should they....
a) Check everyone BUT YOU?
b) Check no one and just let theft continue?
c) Check only people who look like they have theft ON THEIR MINDS?
What would YOU do if you owned a store?
My thing is don't ask to check my bag or any bodies bag. How can the store be respecting a customer when at the same time they have assumed that simply because a person has come in with a bag that they come in to steal.
If I had a store I wouldn't treat people like they've come into my store to steal.
