Fill out the survey at the bottom of your receipt and mention him in it. He will be commended.
Call and speak to manager
You can call corporate office. They have a department for that
I thanked him profusely and then told the cashier at checkout.
Best way is to write a letter to human resources, corporate office, with a copy to tje local store. Telling a cashier or a manager wont go anywhere, as they may get busy or distracted and whatever they promised to say or do may not happen. A nice commendation letter will go in their personnel file, and looks good if they are ever up for a promotion.
Call the store Manager let him know then ask for the corporate number and go from there...
