I saw this sign posted on Facebook last week and thought, “What an ingenious way of convincing people to engage in kind behavior.”  

The sign tells customers that the deli is willing to tolerate unkind behavior, but it would be at a cost to the person engaging in that behavior. In other words, “If you make our day instead of making us miserable, we’ll make it worth your while.” According to the copy above the sign, this message had an immediate impact on customers’ behavior. There must be other nonthreatening ways that we can communicate to people that it’s in their best interest to engage in kind behavior. If any examples come to mind, please share them with me. Thank you.
