They must be heavy as even the plastic ones weigh a ton and even they are not so easy to install. I've been grossed out by busineses who put plastic on those commercial stations without bothering to even wipe them out from the road and storage dirt and the machines used to cool and heat the water from the jugs are full of hard plastic components, heat the water, which is even worse, and are rarely cleaned up - I always carry water with me for that reason as even a plastic bottle is better than drinking water from there!
