Which employee has what it takes?

Last night my wife and I went out to dinner on Lake Minnetonka. We pulled up to the restaurant via boat. There was a wait to find a spot. One of the dock guys says, “just wait your turn it will go a lot faster for you than staying close to this side of the dock.” The other dock guy says, “I will work with you and find you a spot.” He adds, “I am going to move this boat forward and you pull in right behind.” The original dock guy simply looks down an realizes he was not solving the customers problem – finding more space to park. Needless to say the one who helped got a big tip from us and I have little doubt he is the gross and net winner of tips overall! How do you spot that talent and initiative early and develop those people to be the culture of your organization?
