I always took my highest level certs. At the time I decided to retire, those were Adv Nitrox, Deco Procedures, Adv Wreck, and Solo Instructor cards.
Prior to that, I did my first trip as a DM and took that. Then, when I got my first instructor cert, I took that. Only once did an operation ask me to buddy up with a new diver.
I told them it would be $50 per dive, my boat fees would be refunded, and the diver would need to fill out a liability release waiver. I didn't dive with him.
After that, I always told the op in advance communications that I would not accept being buddied with someone.
Now, there were times on shallow dives where a diver would ask if they could dive with me themselves, and I did. It was fine.
But I also made it clear that I wasn't changing my dive for them. As long as that was understood, we'd be cool. I even did one with a diver who blew through their air in 30 minutes on a planned one-hour dive, and I took them back to the boat and continued my dive, after seeing them safely on the boat.
On deep or wreck dives - never with an insta-buddy.
Showing an OW card as an instructor is stupid. If it's because of being afraid the op would make you take a new diver, you probably don't have the self-confidence and good judgment necessary for an instructor to begin with.
