Amazon begins temperature checks and will provide surgical masks at warehouses

Our local grocery store chain (Wegmans) finally let workers wear masks last night, as well.

The Trader Joe's near me took the most serious steps so far. They are limiting to 30 people in the store at a time and setup 'lanes' six feet apart for carts to lineup for checkout. When you checkout, they take the cart and have you stand back while they ring up and bag your stuff. When it's time to pay they back up from the register and let you pay and take your own receipt. I say these are the most serious steps because the other grocery stores near me haven't changed much of anything last time I went to them.

It was a little weird at first, but I am willing to go through whatever hoops to make the grocery workers comfortable.

How does the process described help prevent the issue of an infected person placing grocery items in the cart while shopping, only to have the cashier touch them at a later point in time?

It doesn't, but it helps keep people separated. I did notice each cashier had their own bottle of hand sanitizer, so that could help if they used it after each transaction. Personally, I would still want gloves and a surgical mask if I were them.
