Stop in for a cup of coffee

So. Many years back, guy wants to replace his battery under warranty. Had it only a few weeks. Shows up at a very busy time,other 2 parts guys are out to lunch. Store full of customers, i hastily test battery, its 100% perfect. Customer insists battery is faulty, and backs his opinion by stating hes a nuclear scientist. I load test battery, load tester is smoking and battery is holding with no sign of failure. would not accept it. Wants a new battery. I call supplier, they ok the replacement.

give him the new battery,bookkeeper in the back of the store was amazed that i didnt lose my cool,and same went for a few customers that took my side.
Two week later, same customer walks in with a starter in a box....
You have no idea how much i wanted to kick his ***. at the same moment i felt vindicated.

If it was me, i would have gone elsewhere for a starter.

nuclear scientist? My ***.
When he came back in, Should have been sorry, we don’t sell that here.
