Why do we have division of …

Division of labor is essential to economic progress because it allows people to specialize in particular tasks. This specialization makes workers more efficient, which reduces the total cost of producing goods or providing a service. Additionally, by making people become skilled and efficient at a smaller number of tasks, division of labor gives people time to experiment with new and better ways of doing things.

Returning to the example of the restaurant visit, consider how much longer it would take to have dinner if the same person came to greet you at the door, led you to your table, brought water, took your order and then went to the kitchen to start chopping vegetables and cooking your pasta. A 45-minute meal at a restaurant that divides labor may take a couple of hours at a restaurant where every task related to your table is completed by one person.
