Chick-fil-A is beating every competitor by training workers to say 'please' and 'thank you

The secret to Chick-fil-A's success is as simple as saying "please" and "thank you."

The chicken chain is statistically the most polite chain in the restaurant business, according to a QSR Magazine's annual drive-thru report released on Monday.

Employees at Chick-fil-A were the most likely of the 15 chains surveyed to say "please" and "thank you," and to smile at drive-thru customers. Chick-fil-A workers were also as the second most likely to have a "pleasant demeanor," only topped by the up-and-coming fast-food chain PDQ.
