Walmart almost never, it seems, opens enough checkout lanes. “Update: Walmart prepares for the beginning of school year rush by opening a second register” was posted on Twitter by BSU Daily Snooze on August 21, 2012. “It was so slammed at Walmart today that they briefly considered opening a second checkout lane” was posted on Twitter by Patrick Mead on December 19, 2016.
   
“Due to panic purchasing, Walmart has opened a second checkout lane” was posted on Reddit—Oneliners on March 11, 2020. The 2019-20 coronavirus outbreak had caused panic purchasing.
     
“Due to panic buying, Walmart has opened a second register” is another form of the saying.
 
“Area 51 is where they keep all of the Walmart cashiers” and “Walmart will be closed Christmas Day so both cashiers can be with their families” are other jokes about Walmart cashiers.
