Not quite on your baller status but I use Diplomat fountain pens and I always have to bring extra Bics along in my briefcase in case clients have to sign something. Clients NEVER bring their own pen to anything. I've learned my lesson very early about letting them borrow my fountain pen. Most of them have no idea how to write with it and they end up ripping the paper and ruining the nib. Fucking savages I represent. Why do I put up with them?
Hang on, you like to write with a pointy stick and your clients who prefer precision, modern writing implements are the savages?
