For decades, Walmart was known for its greeters and the 10-Foot Rule that was implemented by Walton. Hot on customer service, Walton instructed his staff: “I want you to promise that whenever you come within 10 feet of a customer, you will look him in the eye, greet him and ask him if you can help him".

In 2019, the company drew criticism when it scrapped the greeter position in many of its stores. New roles were created in its place, which required staff to be able to lift 25lb and clamber up ladders, among other more strenuous responsibilities.

The Equal Employment Opportunity Commission said the change would disproportionately impact greeters with disabilities and sued Walmart. As part of the resulting settlement, Walmart changed its reassignment policy and paid $80,000 (£66k) to a worker who had been let go.
