Yay! I now have a chiavetta, a charge key for the coffee machine.
Instead of, say, human resources giving you a key when you start, they are dispensed by the company that owns the machine. As the omino from the coffee company comes to restock the machine once a week, you have to wait till you bitched about it enough to enough colleagues that one of them remembers when they see him (thanks Maura!) and hope they find you quickly quickly enough for you to run, catch him, and buy the key for 5 euros before he disappears.
