Tonight as I was walking back to my hotel I noticed a well known cafe in King St Sydney had 75 empty 2 litre milk cartons waiting to be put out in the rubbish.
I got thinking. 150 litres is a heck of lot of milk in one day. They do fairly small coffees there, so assuming 150ml per coffee, incl wastage, that's 1,000 coffees in one day. If they do 2/3rds of their coffee trade between 7am and 11am, that's say 165 coffees an hour, or one every 22 seconds.
I think that's a little too quick for even a super efficient line, perhaps 30-40 seconds is the limit? So either they waste a lot of milk or they average a lot more than 150ml per coffee. (Or they don't get rubbish collected daily and it includes Monday's waste as well)
I've got no idea what the answer is, I just found it interesting to think of the quantity of milk being used. (Procal BTW)
I can only imagine how many kilos of coffee they get through, perhaps 20?
