The worst thing you have ever heard or seen...

1. On a week long live-aboard, dude on the granny-line performing a major aqua-dump.

What has been seen, can not be un-seen.

While I'm sure he felt relief, I nearly drown myself laughing/breathing through my regulator.

2. Barfing through my regulator. It can be done. It ain't pretty.

On our first dive trip as new divers, one of my dive buddies didn't know he could puke through his reg. We were in heavy seas during the safety stop, and he took his reg out, chummed, and put it back in. For a novice, on an advanced dive, he was a champ.

Recently? At the quarry, TWICE, I've been just going nicely along minding my own business - OW students tried to stand on my head.

They came out of nowhere and went vertical on my head.

Happened on two different days. I tend to swim looking down a bit. That habit saved my mask in both situations. I used my arm to push them out of the way. I commented to my dive buddy after the second time this happened, that next time, I start pulling fins.

Idiotic instructor to let them do that. I have white fins that damn near glow in the dark. Shallow side of the quarry, usually a lot of light even if viz is bad. No one can say they didn't see me.

EDIT: These were large groups of students. Probably from one of the shops I refer to as "diver factories."

That isn't just for new divers. I was diving with a group of DIR divers on a wall once. Two of them had Tech 2 ratings or higher. Several times I had to push them away as they dropped on top of me while I was photographing critters on the wall. Their situational awareness was only what was on a plane in front of them.

very common at every level
some people just don't care about their surroundings

same with many underwater photographers: on the barrier reef I witnessed many divers super busy while taking the perfect picture of their favourite fish, and in doing that they were laying on corals or other creatures braking and making a mess
I don't have faith in the human beings, therefore I think they just don't give a flying f0ck

Yup... crunch-crunch as they lock each elbow into the coral for a steadier platform, then utterly engrossed as they focus on getting the perfect macro video footage.
Oblivious to dive time, remaining air, other divers in the group, their buddy, beckoning mermaids...

I was doing deco on the shotline in Croatia with 7 people of our boat after a wreck dive (Wreck was max 147 feet deep). When a tank suddenly came down from the surface, Almost hitting a guy that was doing deco with us, it was a close call! (it was a emergency tank some boats drop before the dive). A few minutes later some sport divers with bad buoyancy/trim and single tank (on such a deep dive??) configuration came raining down, one of them had doubles which was probably the guide. After 10 minutes they came up, we where still doing deco on the shotline. They ascended while holding the shotline and it looked like pure chaos, then 1 diver dropped his camera. He tried to go after it but went out of air and he tried to swim the surface, the guy with the doubles donated his primary and pulled him back down (a little bit of deco? safety stop?). They surfaced before we did. When we entered our boat, the guys on the other boat just acted like nothing happened. Like it was normal for them.

I can tell you, the deco time wasn't boring at all on this dive...
I don't understand why divers would take so much risk, and that for a such a short/chaotic dive. I know for sure they didn't get to see much of the wreck.

A whole club of divers who thought it was a good idea to dive twinsets, the manifold shut with 50% in one side and air in the other.

So when they go into an air share, who toxes and dies?

Well they have two regs coming off post... because you know, "redundancy" and the idea is you play Russian roulette with the remaining 3 of posideon regs (if theyre not already freeflowing) and hope to hell you don't start doing the funky chicken.
