For example, if I track it well it will give me an opportunity to contact the customer and "say your 1 year warranty is up is everything good". This I think will leed to oh while your here can you have a look at (fill in the blank). Thats why I thought I would ask the ECN family what they thought?
That's a good rule Greg. This shows why it's always good to be courteous when you deal with customers, and to be courteous when you ARE the customer. I am so much more likely to go beyond what is expected of me when a customer is nice, polite, and thankful.
