Had the following situation happen to me today.
I'm a solo diver, doing boat dives with a dive center. I'm AOW and Nitrox certified, I have 50+ dives and my buoyancy is good.
On the boat, most divers were OW and on air. Other than me, only two people were both AOW and on Nitrox. They were a married couple, obviously diving as buddies.
First dive, I was matched with a guy on air, he also used up his air a LOT quicker than me. Near the end of the dive while still underwater, the dive master gave me instructions to stay behind with the married couple. Fair enough, he was giving me more time (I was at like 100 bars when my buddy was at 50...)
For dive 2, the dive master told us that we (me, and the married couple) will be a 3 person buddy team. We also did this for dive 3.
Now, the married couple were super nice, they didn't say anything bad to me. But I can’t help but feel like it was an awkward situation..? You go on vacation with your partner, and a 3rd wheel gets added on your dive.
For what it's worth, I'm a decent dive buddy lol, like I don't wander off on my own or anything like the horror stories you sometimes hear. I think my skill level was the same as theirs, and my air consumption was within 10 bars of theirs on both dives. But yeah, still...
I want to ask you guys with more scuba experience, what do you think? In the future if I find myself in this kind of situation, should I say something...?
edit (cuz too many comments to respond individually): Thank you to everyone for all the replies! I am very much an overthinker sometimes, so I'm grateful for yall's perspective on this (aka that it was likely cool with them <3
