A bloke at our place showers every day after work. We finish at 15:30, he blows up if a job runs over and we are not back in the the yard to shower in works time.
After showering, he fills up a 10 litre container of filtered water and a small esky of ice.
He is also known to take teabags, coffee, biscuits and sugar, yet is the first to complain if we run out of anything.
