Back in the 70s, when ferries were a bit more barbaric than they are now, I had a traumatic 28 hour Irish Sea crossing. As soon as the vessel left the harbour, sick bags were being handed out. These were basically paper bags, much in the style that sugar is sold in, but a bit bigger and open at the top, ready for filling.
These receptacles soon were fairly full, and, with the violence of the ship's motion, there was no means to dispose of them, so they were propped up all over the place, ready for topping up, as necessary.
On several occasions, I saw people carefully lift up their bag, to add to the contents, only to have the base give way and deposit about a litre of (now cold) puke, straight into their lap.
I will always remember the slogan emblazoned on the bags - "For Your Convenience And Comfort"
