I used to work in Vancouver on residential towers. A couple of hundred trade workers sharing 2 or 3 portable toilets on the ground level and a 30+ minute wait for the skip. If you were lucky they would bring a half-toilet up to the 15th floor. Sitting there taking a with a view of the ocean and the cool breeze blowing in your face. It truly was magical.... and everyone can see the look on your face when they come running down the stairs ready to piss their pants and you're still pinching a loaf.
