Thanks a lot for your ideas!
- Raw milk is recommended to be boiled before consumption.
- It is recommended that raw milk be boiled before consumption
Is the red just other possible (better) way how to say it or is the black one (mine) not recommended at all? (Just wondering.)
- The milk is being dispensed as long as you hold the button pressed. (Milk will be dispensed only when the [red, white, blue, big, small? Which button has to be pressed?] button is pressed. Is this true? Isn't there a limit to how much milk will be dispensed?)
There is only one button so I think it's not necessary to specify it more. The key point of this particular instruction is to say the customer that he has to HOLD the button. As long as he holds the button, milk is flowing. It stops when either the customer runs out of credit or releases the button. How would you write this?
There is an animation together with the text instructions ;)
