It all depends if the restaurant owner had a reserve and could withstand an extended closure. I've seen some restaurants that have re-purposed their business to offer take-out (limited menu) and using some of their staff to deliver. Proactive social media, etc. There will be a shake-out and wonder if the federal or state government offers relief as well (short term loans, etc.).
Was having this discussion this weekend in terms of what businesses will suffer, rebound or even do better.
We have become a fulfillment society (Amazon, etc.) and this will only give people another reason to use these services which do not seem to have let up (in fact I read that Amazon is hiring thousands right now).
You can predict companies that offer turn-key WFH capabilities.
Travel and tourism will take a hit an take time to rebound although with people forced to stay home there might be some pent up demand to get out of town once there is consumer confidence.
Meeting planning and entertainment as well. The minute it's safe to go back into an arena/stadium, there will be packed houses. Sports gambling...will probably spike when the first game is played. Companies will go back to their travel/meeting schedules although they might look more at Skype and webinars.
In healthcare, telemedicine adoption and growth will likely grow dramatically (which is a good thing as it will have a major impact on reducing the cost of care while improving outcomes). Personal protection/care will be looked at hard to ensure that we have a pipeline and stockpile.
Anyone notice gun sales have mushroomed? Don't expect any meaningful gun legislation by the next President and Congress.
