Exactly. Do I agree to a body-cavity search when I walk into a place of business?
There was a case not too long ago about women being filmed changing clothes at a Hooters. Well, if I give consent to searching my car when I drive into the parking lot, how is that different than a search of my person while I am changing clothes? Where is the line here? I put the line at anything in a locked container.
You do when you come in MY store.
But then again, I'm a perv.
