Glass cleaner functions

At the weekend, I was discovering one of the most important human fails. Everybody know a Glass Cleaner bottle:

All glass cleaner bottles let you change the way to expel the valued liquid. Some bottles has two functions, three... BUT, there is an important fail here. One of the most important design fails will be show below. But first, I show you the main functions in a glass cleaner bottle:

1.- SPRAY function:

It's the standard function. It let you expel water with a spray form. No more.

2.- STREAM function:

It's the secondary function. It let you expel a water jet. All right.

3.- OFF function:

Oh, SHI***!!! IT NEVER WORK!!! GUARANTEED!!! FUC***!!! WHEN YOU PRESS THE BUTTON, SURPRISE! A WATER JET ALWAYS WET ALL YOUR ARM!!!

Unforgivable...
