Talk about taking the piss

It's less a urine thing and more a vomit thing. 

Do Ryanair charge to use the vomit bags too?

Nah they just recycle them amongst the passengers.

I do recall from my RAF days we used to put vomit bags in the seat back pouches whenever we carried passengers.
On one occasion I enjoyed the sight and sound of a very upright Sergeant Major ordering his about to deplane troops (95 Grenadiers if memory serves) "And take the fecking Sick Bags wiv youse 'cos we don't want the Brycreme Boys knowing how many of you fecking nancies puked up during the flight" and every soldier carried off his sick bag, used or not. Given that the aircraft stank of vomit I reckon most of them had used the bags.

  Flying back to the UK from Singapore in the late 60s on a DC-10 we hit an air pocket...Most of the sick bags were used, I have to say that I was very, very young at the time....
