Now which button would you push?

Life can become so complicated, even with the most basics of life's necessities. I eyed the buttons with some concern, but it was the only cubicle free. The heat-warmer seat was an unexpected bonus. Luckily, I made sure that I was decent before I guessed which button was the flush. Out popped a fountain-like spray & I jumped out of the cubicle with a few yelps, watching helplessly as the spray began flooding the floor. The poor cleaner just shook her head, as she must have done a number of times, at us unsophisticated foreigners.
