And at least one Weatherspoons (chain pub). Sad when that one shut down - though it's possible the new multiplex had the same owners.

Neither of those are sparkling businesses during the pandemic

They don’t have to be. The buildings will still be there, it’s the debt securing them (and equity, depending on the capital structure) that’ll eat the losses until they’re repurposed at some point in the future.

Assuming they’re secured and maintained enough to avoid vandalism and damage. Once water/mold start getting into abandoned buildings there’s only one option left eventually.
