Aside from the trust issue, there is an implied business agreement here which, for me, goes something like: We pay you money. In return, you allow us to use your premises and equipment, you look after us while we're there and you lock up your own premises when we leave.

I don't see why the second part of this should be part of the transaction. Owner is trying to keep your costs down. If you want to be looked after offer some more money and ask for someone to be there. I've used a place like this, leaving the key under a brick! Mad, yes, but not a problem.
