i. The preferred ratio of coke to coffee,
ii. The preferred temperature of each component liquid (separately and/or combined),
iii. The relative pricing of the component liquids (see Appendix I),
iv. The desired quantity of the resulting combination.
It was agreed that we would look into the possibility of providing an alternative container for the combining of the two liquids. [Action point: JM to investigate.]
In August 2003 a 330ml container ('can') of Coca-Cola ('coke') retailed from Cambridge Vending Machines Ltd. ('the drinks machine') at £0.50.
Coffee followed a more complex pricing matrix, viz.:
|BLACK||BLACK WITH SUGAR||WHITE||WHITE WITH SUGAR|
|Instant Medium Roast||£0.00||£0.00||£0.00||£0.00|
All types of coffee are sold in the same measure, that is, "small plastic cup".
