Ever been dropped off?

[plmnwater]

When diving with my cousin a couple years ago in Key West with Southpoint Divers, we were heading back to the pier. We happened upon a couple divers sitting in the middle of nowhere, miles from land. They had been dropped off to do an advanced dive while the rest of the boat went to a different location. Our crew refused to let them sit and wait, and pulled them onboard. We then drove them to their boat, which was quiet a distance away. Would anyone here knowingly let their boat just drive away while they were underwater? I certainly wouldn't.
