Caudi, 2 of the 3 locations have closed, not just 1. If it wasn’t clear in my post, what I thought might discourage ordinary customers would be the Secret Service closing down the restaurants or requiring customers to be screened, not the politics of the POTUS or VPOTUS visiting the restaurant. Ronald Reagan didn’t attend church during his Presidency for this very reason, and I wouldn’t be surprised if the Obamas seldom attend a local church (when they are in DC) for the same reason (Clinton, OTOH, might have been afraid of lightning bolts, ). I have a half-hour lunch break (other people have a full hour). If I know the Chipotle location I visit occasionally is going to be closed down or have significant delays on an unpredictable but somewhat frequent basis, I’m going to give up and go elsewhere. If enough customers are discouraged from visiting (and tell their friends of the inconveniences) it would impact the restaurants’ business very quickly.
“… a dispute between the restaurant owner and the landlord,” covers a lot of possibilities. Maybe the landlord wouldn’t fix a leaky roof. Maybe the lease was up and the landlord wanted a rent increase wile the tenant wanted a rent decrease. Maybe the landlord wanted the rent to be paid while the tenant didn’t feel like doing so. Or maybe they couldn’t agree what the phase of the moon is.
