^ Last few times I've been they were stopping Wicked to go on flip flop and hat runs at least a few times while I was waiting in line. It might not be all the time. But it has happened a few times that I've gone to Lagoon that someone loses their flip flops and they stop the ride to go get them. Happened 4 times in a row one visit to Wicked (they started, ran 2 trains stopped to get hats, started up again ran 2 or 3 trains, stopped to get flip flops, etc.) I also lost a hat on the ride and the ride ops offered to stop the ride to go get my 5 dollar hat, lol. Also happened twice the last time I rode Roller Coaster while I was waiting in line. Twice. It might be inexperienced crews or a lax day, but I don't think this was the designated "stop to go retrieve all items lost on a ride" time, maybe it was, but that wasn't conveyed to the line very well.
They also don't let you utilize the single rider line as easily as it should be on Wicked. Lines wouldn't nearly be as long if park employees actively shifted people into the designated group/single rider line.
