There are different methods of counting how many people can enter, so there's no sure way of going straight in once you arrive. As an example, Target is monitoring the number of customers in each of its 1,868 locations to determine whether customers have enough room, based on square footage of each store. Once a store reaches its safe-spacing capacity, an associate will establish a waiting area outside the market, while another will monitor checkout and guide new shoppers inside, making sure one new customer replaces each one leaving.
Meanwhile, Ohio-based Buehler’s Fresh Foods is hoping to create a helpful and up-to-date information for its customers. Before leaving home everyone will be able to look up the 'best time to shop' chart, divided into 3-hour slots for every day of the week, calculated individually for every Buehler’s store. This way grocery planning should become easier.
If you're unsure about when stores around you are packed and when shopping is easiest, there's very good advice from customer data firm Retail Aware. The brand has sensors placed on shelves of shops across the US, monitoring traffic through heat and movement detection.
