NEW YORK—As New York, San Francisco, and a few other cities and counties require restaurants to check proof of COVID-19 vaccination to dine indoors, some fast-food chains are simply shutting their seating areas altogether—a move that may dent their sales.
The burger chain White Castle shut the seating sections in its more than 20 New York City locations in September, after New York City began asking customers over the age of 12 to prove they received at least one does of the vaccine in order to eat indoors.
