Very bad, IMHO, that they're so inconsistent on this (like everything else). As you saw, you usually have no warning until it's too late - it can be difficult, if not impossible, to see what the TSO is doing with your wallet.
I still had to go through the metal detector though. When there is no NOS i don't have to take out my wallet. I guess that is where my confusion has lies.
I'll just start throwing it in my backpack... or skip flying out of MKE
