The ability not NOT follow any instructions…
Me: Your car needs the oil changed, you need to take it in. Do NOT let them do anything else to it besides changing the oil. (This, after she had previously spent $50 on a goddamn $5 cabin air filter.)
Her: (Calling me from the shop.) They recommended flushing the radiator. It’s $75.
Me: What did I say? Do NOT LET THEM DO ANYTHING ELSE.
Later that night…
Me: So how much did they charge?
Her:They flushed the transmission and “cleaned” it. It was $250.
