Not working now so I can make them whenever Na'Quis lets me ;-) at work though the office used to have a tea-kitty which as the admin bod I used to collect and then use to buy tea, sugar, coffee, milk. As it was a fiver each a month and had been running since before I started there we had a nice surplus and used it to pay for Christmas meals leaving do's etc as naturally it would get topped up again during the year.
