It would be great is you can give 1 requested item at the time as soon as an item is ready. For instance; in the plain 30 sucre is requested. Now you must make 30 sucre first and give all at once. But sometimes you have not enough storage to store 30 sucre first before giving it. In that situation it would be nice if you can give 1 item at the time. So you dont have to store all requested items first.
