There's a message or three or seven in Jim W's message:
One never gets tired of positive feedback/appreciation/recognition. (More precisely, "Thank yous.") Spontaneous Acts of Thoughtfulness are Mighty Love Bombs. SATs are MLBs that can lead to stratospheric profitability. SATs are at the Heart of repeat business. I'll [literally] remember Jim Warren, "the O'Hare guy," until my last breath. I'll talk about Jim Warren until my last speech. The fact that JW went to the effort (a) to call, (b) to call from the airport, (c) to go to the trouble of finding me adds multiplicative power to the act.
