>There will be many profitable restaurant businesses who find their business lacking liquid cash over the next few months

Like I said in my earlier comment, the best hope for these businesses is to return to normal revenue numbers. They aren't going to make up for the business they are currently losing. They don't have a liquidity problem. They have a lost revenue problem. They are still accruing costs without accruing revenue. Delaying those costs doesn't fix that disconnect.

>Paying down the debt is a common business practice that people do all the time.

Taking on debt to allow you to make investments and improve future outlook is a smart business decision. Taking on debt in order to meet recurring operating costs rarely works out when there is no hope of future growth.
