How many people who would normally go there will now say something like "why risk it, I'll just buy food in Lakewood". It can completely kill the financial viability of the business, he may as well cut his losses now instead of bleeding cash for a few months before closing down.
The store has been takeout only since COVID started and there have been extraordinarily long lines without visible volume to cause it, it’s possible it was heading towards closure anyway. However it’s super unlikely the owner made a split second decision to close up shop permanently just because of an allegation even if your svara is reasonable.
I would say it’s much more likely there’s something more serious prompting it (possibly was going to close anyway and this is the makeh bepatish, or perhaps there is actually raglayim ladavar).
