A study a few years back of over 1 million online reviews of 840,000 restaurants turned up an interesting finding: Diners gave worse ratings when it was raining. “The best reviews are written on sunny days between 70 and 100 degrees … a nice day can lead to a nice review. A rainy day can mean a miserable one,” researcher Saeideh Bakhshi told The Washington Post. The obvious takeaway: Move your store to Hawaii. Failing that, best to ask for reviews on nice days.
