It's entirely possible the new normal will indeed be times of open business, times of closed business. Think of jobs that are seasonal - people hired for a chunk of time only. I lived in a coastal New England town that thrived in the summer - and people I knew worked made as much money as they could during tourist season in order to carry them through the winter.
Not saying every business model will be set up this way, but in an age of uncertainty, being able to be more fluid will separate the wheat from the chaff (or whatever the old saying goes).
Did I mention that everyone I knew in that coastal New England town had a full liquor bar in their houses to get them through the winter? Just sayin.
