i have been having good luck with getting them to watch my bag for me. I put a locking strap around the bag and my own locks. I have a lunch bag with cold cheese & fruit inside i am taking to my gramma.
They want to see the cold bag! They will pull my bag aside and watch it until I can get over to unlock it from my opt out. So they only thing anyone could steal is my shoes and ditty bag. But they usually keep them together.
