that sounds like the best way to run a supermarket!Where you live has a lot of impact on how the situation is being dealt with. Here in PA we have been shut down since March 13 but the numbers are still going up.
I went to the local grocery today. They have really been proactive in halting transmission and helping customers. The manager posts on facebook when the deliveries come and what has been shipped. They provide wipes, gloves, and masks if you want them as well as keeping some items in reserve for seniors and medical workers.
On the other hand some were complaining that people are getting take out and sitting at the picnic tables to eat.
Some how we will manage to survive this.
Keep your distance.
Creates a safer environment, and fulfills the obligation to staff and customers. ( to the best available)
Safe customers would generally spend more and make more referrals as well... so the masks and other costs will return a profit easily.
