We are currently still doing carry out delivery business, but are still 65% down.  

Restaurants and grocery stores have internet purchasing infrastructure that drives delivery or pick-up from their retail locations.

Each and every time I gave my client my clients the reasons why, employees quit, fired or didn't show, I underestimated the time needed, ran into issues with material delivery, doesn't matter the reason I always let my clients know and gave them a new deadline, which on the second time around I would 100% make sure I made.

I grew and lived here, and worked as well doing deliveries in my earlier years (grubhub mostly)..

In saying that, most people have short memory.I think working from home and food delivery facilities will be attractive. 

Oil producers aren’t selling oil at negative prices, speculators are selling to close their futures positions prior to expiration because they aren’t able to or don’t want to take physical delivery of 1000 barrels of oil. 

Most options traders don't want to actually take delivery of oil so they sell, because the option is about to expire worthless and they don't want to get assigned. 

Is this a viable strategy or are operators going to be much more demanding about delivery condition?

And if they won't even respond, I would send them a certified letter (w/ delivery confirmation) saying just that.
