"I don't have a great deal of sympathy."
I think you've missed the point Lass -- the issue isn't whether or not those on a night out should or should not pee before leaving a bar, or whether or not public facilities should be provided. The point is that given that public facilities have been provided, why there are vastly more for men than women............
I'm sure you know this Lass, and are just taking the wotsit.
And same occurs in the city I am currently in, where at times of great public celebration, temporary urinals provided for the chaps, but nothing for the ladies. Equal provision should mean equal provision, not '....and the ladies can piss in the gutter or not at all!' Which is weird given that in my experience, some men seem to prefer en plein air pissing to anything else......................
