P-Mate. Too scary (but for all the wrong reasons, ’cause it looks like a brilliant solution to an eternal problem).
‘No toilets available when in desperate need of one?
Always standing in the wrong line?
…The unique and original P-Mate which enables woman [sic] to pee while standing upright. Once you have used it, you can’t do without it. The P-Mate is made of environmentally friendly, fully recyclable material. The P-Mate should be used only once.’
