Looking back there were a lot of people who looked like Marty Feldman by the time the driver pulled over.

This morning I took a wazz in a remote Welsh layby. I parked the car, then ducked under some trees into a little hidden culvert.
Unfortunately, someone had earlier had the same idea. There was a sloppy pile of hum0an turd, but with no accompanying evidence of toilet paper. I assumed no paper was available, so they just pulled up their keks and trousers, and off they went.
Quite a successful wazz with no interruptions, for me.

After doing the business, you can surreptitiously empty it anywhere without most people noticing.

If u used it at a busy train platform, most feckers wouldn't even notice as they read their copy of the standard.

And if u did empty it at the terrace of a vegetarian restaurant ? Most people would just think that angry pink-haired Karen the chef had just strained her vegetables.
