how hard would it be to unplug the units? if these things are on a shared electrical circuit with anything else in the store, then that's on them. If they are separated, then just flip the breaker. otherwise, there's going to be j-box some where near the thing connected to some conduit. ten gets you twenty that there's some wire nuts in that j-box that could be disconnected in less than a minute.
also, just show up with a clipboard, and if anyone asks you, just say you were hired to collect certain items from within but not remove the entire thing. just print up a fake work order. i don't think i'm thinking too far outside the box on this one.
