"David Hensel, a single father of six and a food stamp recipient, has cut back on the number of trips he makes to the grocery store each week. He also wears gloves and a mask each time he goes.

Still, he worries.

'Every time you walk out of your house and go somewhere, the potential of bringing it back is there again,' said Hensel, 57, of Chicago’s West Rogers Park neighborhood.

Being able to order groceries online and have them delivered would mean he could avoid that risk, he said. But that’s not an option."
