In 2001 I met a girl from a chat room who worked at Enterprise. She was just newly divorced from her high school sweetheart, and had never done anything with any guy before other than him.
I drove out to meet her, we messed around in a parking lot in a closed strip mall. She blew me, we messed around some more, and she was very happy with the evening and kept begging me to see her again. She was also incredibly easy to please because apparently her husband didn't know what the fuck he was doing all those years.
We had plans for the following Friday, but sometime during the week, I offhandedly mentioned on the phone what a scam car rental insurance supplementals were. Keep in mind the insurance was only like $9 at the time, but even at that price it's a huge ripoff. Nowadays it's just LOL how they sell you awful $25-$40 per day packages.
She kept insisting to me that it was a great deal for the customer, that I didn't know what I was talking about, and was getting increasingly agitated with me for disagreeing.
Finally I got annoyed and said, "Okay... $9 per day. Multiply that by 365, and you're looking at like $3300/year. That's the yearly rate you're paying, and all you're getting for it is collision coverage, and nothing else (this was before they offered other insurance). Would you ever buy a car insurance policy covering only collision for $3300/year?"
She got really pissed at me, told me I was an asshole, said she didn't want to see me again, and hung up.
I'm guessing she probably went back to her husband after that.
