Walmart announced some policy changes to keep shoppers and employees safe from the coronavirus. Dacona Smith, Walmart's Executive Vice President and Chief Operating Officer, explained the changes on their company website:

Starting Saturday, we will limit the number of customers who can be in a store at once. Stores will now allow no more than five customers for each 1,000 square feet at a given time, roughly 20 percent of a store’s capacity.

To manage this restriction, the associates at a store will mark a queue at a single-entry door (in most cases the Grocery entrance) and direct arriving customers there, where they will be admitted one-by-one and counted. Associates and signage will remind customers of the importance of social distancing while they’re waiting to enter a store – especially before it opens in the morning.

Once a store reaches its capacity, customers will be admitted inside on a “1-out-1-in” basis.

 Smith also said Walmart is creating one-way aisles:

We’ll also institute one-way movement through our aisles next week in a number of our stores, using floor markers and direction from associates. We expect this to help more customers avoid coming into close contact with others as they shop.
