Desserts are in limited supply. Desserts can be given to any customer, but some customers will specifically request them. Make sure that you save enough desserts to fulfill all customer requests before you start handing them out to just anyone!
Consider using coffee while customers are seated, or the podium while customers are in line to keep them happy to avoid using up all of your desserts too quickly.
Ariel is a To-Go customer who will always order desserts. Some of the VIPS might also order desserts from time to time. Make sure to serve dessert requests quickly, as they will time out if not fulfilled fast enough. If you do not fulfill a request, the customer will lose a heart.
