New set up and animation flow for fast food restaurant

the real world fast food, there are couple of staffs at back making burgers and fries, then put finished products to a storage shelf behind customer service staff whom just a simple turn around to grab fresh made burgers fries and drinks to assemble a meal then present to customers.
can we have this animation displayed in store instead of customer attendant move around the griller to make a meal themselves. there is a teamwork in store not everyone work by themselves.
to achieve this, you may need to buy a shelf as a required furniture in order for store to run.
a food shelf perhaps
or make this shelf as a boost function to your business (eg. serve more customers, increase income by a certain percentage)
you can assign one staff to this shelf to operate, or two staffs to a bigger shelf.
investment is worthwhile because this furniture increase income by serving customers more quickly.
