I think that it is the correct measurement that is taken from coffee shops and restaurants.
It is not the way that Corona virus is going to be eliminated but it is a way to make a routine to use hand sanitizers and keep our hygiene levels at their highest.
Hygiene levels at highest, right

Viruses spread easy with something lots of people touch, like touch-screens. They are everywhere like ticket-machines, self-service checkouts, cash deposit machines and restaurants like Mc Donald's...
They also dry and a bit warm so close to perfect temperature for the Virus.
On that note, (cough, cough)
