CHICAGO — Walgreens will no longer require its cashiers to send each customer off with the words, “Be well.”

A spokesman said the campaign had run its course, though the company didn’t elaborate on why the effort, launched several years ago, was dropped.

“It’s accomplished its goal of reinforcing our branding,” spokesman Michael Polzin said.

“We’ll continue to build our relationships with customers in other ways.”

A memo sent to employees this week outlined other changes in dealing with customers. Among them: Employees should learn customers’ names, they should thank customers for their purchase and they no longer have to say “Welcome to Walgreens” when a customer enters the store. Instead, they could offer a cheery “Good morning” or “Welcome back, Mr. Smith. What brings you in today?”

Some self-identified Walgreen employees have voiced frustration with the slogan over the past year on a Facebook page run by a workers advocacy group. One complaint was the “Be well” phrase sounded robotic.

“I love and respect my customers, and of course, want them to be well, but it’s just not necessary to sound like an insincere carbon copy routine Walgreens worker,” said one poster, who wrote she’s worked at the same Walgreens store for about 12 years.

“This is definitely a step in the right direction.
