Why do people order food in a restaurant and then skip out on the bill – otherwise known as dine and dash? The most common reason is that the server is taking too long with the bill and the customers decide to leave out of frustration and a sense that they will be able to get away with dining and dashing because they think the servers are either busy or lazy. Also, people hear about their friends dining and dashing and decide they want to try it.
