Seems a little bit scare-mongery to me.
Or increase wages. Quantity demanded of labor is greater than supply. It's relatively-unskilled work, so drawing new entrants to the labor pool isn't prohibitive. But it isn't happening at prevailing wages.
That wage increase, in turn, might merit price increases for customers. If politicians find that untenable, they may spread the cost to taxpayers instead through public programs.
If you're involved at any of these levels, reading the writing on the wall would be useful.
Supply is FAR larger than demand right now. Have you seen the unemployment rate right now?
No, they certainly don't. What's necessary is that people get food. How they get it is open to discussion.
That final part where customers perform a random walk around a warehouse until they've found everything is not a "well oiled machine". Better to hire some professional shoppers who know where everything is. It'll be faster and safer.
Even if you insist on remaining open to the general public walking around your store, there's a million things you can do. Some stores are limiting the number of customers in the store at one time. Some stores are requiring face masks. Some stores are marking aisles as "one-way" to make it easier to maintain distance. The last store I was in had plastic film over the payment keypads, and sanitized it between customers. We know how to improve things. There's just not a ton of consistency yet.
