Honestly, I never saw the Arthur movie he referenced, but in that light - yeah, I get it's just a joke. Maybe one that didn't go over so well, especially with all the people like myself who didn't catch the reference?
But when you work for a high profile company that's so worried about virtue-signaling already? You have to realize public comments like this mean you're about to lose your job. It sounds like this guy was a good price negotiator so I'm sure he'll be just fine and get hired on quickly at another company. They *all* like having people on board who can negotiate deals that clearly save them money.
