I wouldn't mind spending a penny to pee but a euro is a bit steep ! I'll pee in my seat ( or worse ) and see how they like that!!!
What if you get the runs, you might run out of euros and that would be really embarrassing ....
So we will all need to put a euro in the slot eh! That is a bit old fashioned Leary, why don't you move with the times ( I do every morning) and issue 'c r a p cards', you could do air mile points too, the more you sh**te the more points you earn....you could also have Leary Loo roll with a picture of your  face on, or failing that Simon Cowel, either will do!!!!
