There's an op that routinely takes OW divers into a cave, on singles, with at most one light per diver. And definitely no line. The entrance to that cave is at 40m. I declined politely, but quite empathically. Several of those who went had worse buoyancy and trim than my son had on his first post-cert dive. Dangling octos on several of them, too.
That was also in Italy.
I'd be quite surprised if they were on RBs.
That's a shop that needs reporting to its agency.
