"We often think about gambling businesses having no income"

- I think this is wrong though, gambling business is a big income business and even though they've closest their casino, they have a lot of money at their disposal. And they could compensate their employees, whether it is a regular paying employee or not. They owe their success to those hard working guys and they should return this big favor to all the people around them. They can definitely cover all the lost they have incurred in this lock down very easily, once everything settles down.
