I've met so many developers who seem to be willing to do anything, except use sql. I remember one case where we were dealing with clearly relational data. One of the senior developers was adamant that we use a non-relational database. When pushed as to why, he said it was because it would have better performance. I pointed out that this for a process where data would be sent out and we wouldn't expect to receive it back for 3 days or so. A few milliseconds performance boost was hardly beneficial over 3 days. But he was insistent and was senior, so we did it. Shockingly, it turned out to be the wrong decision. Later we learned that the senior developer didn't like sql.
