Who’s Fault…

I called a Selectmen after his high usage appeared on our variance report…

• I gave him the specific hours with high use• First - Blamed us

• Second - Blamed the kids

• Third - Blamed the wife

• After the first snow of the year, I called him and told him that his use had remained low that night.

Oops - He realized that it was his engine block heaters from trucks that had previously been garaged at another location.

Customer walks in complaining…

Last month my bill was too high!You must have made a mistake!

Customer Service reps checks account history and asks, “what did you begin doing at about 10AM on January 20th?”

You could see by the look on his face that he knew what the problem was.

He left, then called back a few hours later to see if his use had returned to normal.
