Exactly this.

I had the misfortune of working with a salesperson who only read the "yes" part in an email and sold a lemon to a client for not enough cash.

I protested immediately after the sale (when I was informed of the technical specification) that all the conditions were meticulously described but ignored and presented the email. Management decided to take the risk of going forward. The project failed. I was still blamed for it because by then I was an easy scapegoat.

Never received an apology and lost a good chunk of my reputation at the time. I haven't been an employee and have been my own salesperson since then (15 years ago). Less politics and ass covering between my ears.

Tiny little things like this can make or break you.
