Thanks for the feedback Hernz!
You can drop dice by putting them on the shelf at the top left side of the bakery! You can't put them on the ground, unfortunately, as they're ingredients and we don't want to get them dirty!
You can also throw away the dice by going up to the bin in the middle left-hand side and pressing the prompt there!
If we had more time, we would definitely state in the tutorial that the front face is the one we are meant to be referring to!
