Khushi’s Kitchen offers both vegetarian and nonvegetarian lunch for office workers. The peak period for the business is between 12:15 p.m. and 14:15 p.m. Due to limited space, customers form a queue, pick the food they want, and pay at the end. They start with a single line for starters and then fork out for the main course and fall in line again for the dessert. Since Khushi offers more vegetarian options than nonvegetarian, it takes a little longer for the vegetarian queue. The process flow diagram in Figure 6.10 shows how customers pick up their food during the peak lunch hour and the associated duration of each element in minutes.
