Yep, sent him an idea I had for a project and never heard back. Forgot about it until a year later, he sends me a reply. He must have been filtering through his year-old stuff before deleting, and mistook it for a current note.
In his reply, he curtly told me to check with someone else, as it wasn't his area of responsibility.
To this day, at least 8yrs later, he's still a Grade A, Number 1 asshole.
