It's very difficult to have a landlord with no clear boundaries. I get the feeling we are not the kind of tenants he wants to be working with, or is capable of working with. I have my own share of George stories.
If we want to stay in the space, I would suggest that we be proactive in getting him to modify the lease so that we can all be on the same page with expectations. I think it's also fair to say that we've pushed pretty hard on him as well with what his expectation may have been for us, for example having large events in the common area is no in the lease as far as I know, but he has allowed it to happen, but because we don't have an actual agreement hes coming back with arbitrary enforcement of arbitrary rules.
so we either:
2. make sure that our expectations from and for the landlord are in writing
3. Continue to take his arbitrary rants at random members of sudo room, and just placate (or ignore) him as much as possible (what we are already doing).
