What’s with the Costco crowd on a Monday morning?

I had the morning off so I decided to go to Costco to get some things and when I arrived at 10:30am the places was packed as if it was a Sunday afternoon. What is this madness? Do people not work? Does everyone WFH or not work at this time? When is the best time to go to Costco to avoid the crowds? Why are people so stupid and fail to drive their carts on the right side of the aisle? /end rant
