Finally got the hang of interfaces after watching this tutorial. Haha.. Thank you so much! BTW, I think the output can be used to process some kind of special info / formula from the receiving object - what do you think ?
at 8:40, if you had put your initial message of ingredients in the input, you could have used a print string inside of the "function" over in the baker and printed the incoming message, and also got the return of the baker's message. alot more can be done inside of interfaces, they're a great "tool" to use once you get the hang of it
