I have an aversion to public toilets for the reasons you have outlined Gary; very concerned they will be dirty. Yuck and having to pay for them but I do recall in London paying for them but they were very clean. I liked to get on board early too to put my luggage up in the overhead bin or the little bin next to my seat – I have just flown fourteen hours to Johannesburg and whilst it was a long flight it was pleasant. Sorry to hear of your relatives health decline…sad.
