long lines have formed at our local walmart because of uncontrolled theft by illegal aliens ... they shut down ALL self-checkout lanes, refused to hire enough checkers to handle the volume and refused to implement express checkout lanes ... as a result, long lines of illegal aliens with full carts clogging the checkouts and no possibility for anyone with a couple of items to checkout without waiting forever ... walmart is the only store in town that has now made checkout of a couple of items a near impossibility ... [i delivered my cart to customer service, told ‘em they could put back the [refrigerated] stuff in it, and that i would never come back, after shopping there ever since the store opened 20 years ago]
Several chains tried this in my area, back around 2018, promising to abandon the "impersonal" use of self-checkouts and returning to the good old days of face-to-face customer service. Unfortunately for everybody involved, the "faces" on the service end never materialized. The self-checkouts were back with a vengeance, after a year or so. It was just as you observed about Walmart, i.e., no staffing, long lines and interminable waits, even for a couple of items. I predict the Walmart experience will prove the same.
