the ones around here have strict enforcement, even armed security . They have a maze setup in the store with markers 6-8 feet apart. and every register is open
Haven't seen armed guards here, but then I'm not in at busy times. I think the door 'guards' at Giant are the same ones retrieving and wiping down the carts.
Hopefully going to Yellow will nearly eliminate the outside lines, as they are allowed more people inside. That will be good as long as they open more registers. Otherwise it could be a total clusterf.. with the backup of people trying to get out.
