Trader Joe's no doubt has a multi-year lease at this location that they can't just break. But beyond that I seriously doubt the Trader Joe's legal team inspects the terms of service for the parking apps of all parking garages attached to buildings where they lease space. We'd also have no way of knowing if they objected to these terms in private even if they had.
They probably will have their legal team take a look at the agreement for this location now that it's made the news, but can we cut them a little slack before fetching the pitch forks?
