In determining the type of food service system used by Mr. X, we assess the characteristics of various systems to classify his operation appropriately:
Given Mr. X’s setup selling street food such as gol gappas and bhel puri, he prepares and serves the food on-site, thereby offering freshly made food directly to customers.
This closely aligns with the Conventional food service system.
The Conventional food service system typically involves preparing food from scratch and serving it in a traditional manner. In this case, Mr. X is preparing and serving street food like golgappas/pani puri and bhel puri in an urban slum, which aligns with the conventional approach where food is freshly made and served directly to customers.
