When I was a child my mother would always insist I went to the toilet before we went anywhere, to avoid having to head straight for the nearest public toilet. It never worked. No matter where we went I was always desperate for the toilet by the time we got their, so needless to say, my mom got quite good at finding nice public toilets.
When I was about 14 we went to Lake Garda, Italy on holiday. While there we took a daytrip to Venice. My Dad found a multistorey where a little cash bought us a space in an otherwise full car park, and as per usual I was desperate for the toilet, even though I had been 1hour(?) earlier when we left the hotel.
My Mom found a local bar where we could have coffee and I could borrow the toilet. However, I opened the door to the cubicle, took one look at a hole in the ground and turned on my heals. I would rather burst than go to use the whole in the ground as a toilet.

Years later, and having spend many holidays etc finding publicly availably toilets in the most interesting places, and of different and mysterious kinds, I have almost overcome my oversion to weird toilets. But the hole in the ground... tsk.
We have just come back from a all over wonderfull holiday in France with friends. We had a long drive, but motorway stops usually have toilets, and only once did we come across these being holes in the ground. Luckily the handicap toilet had a normal toilet.
