Here is some restaurant data from OpenTable (HT FBC)
This data shows the year-over-year change in diners as tabulated by OpenTable for the US, the states of Washington and New York, and a few impacted cities (Seattle, San Francisco, and Boston).
This data is through March 12, 2020.
Seattle and San Francisco saw a dramatic decline starting at the beginning of March. Starting a few days ago, restaurant traffic is declining sharply just about everywhere.
Clearly the US will need to help the employees (and owners) of these impacted sectors.
