Captive Market : 

In a captive market, the consumer has no choice about what to buy or from whom. The circumstances force them to buy from a single supplier at a price set by that supplier. One of the captive market disadvantages is that no competition usually translates into higher than usual prices.

Examples :

1. Cruise ships — on a cruise ship, you physically can’t go someplace else and buy other products from another supplier. 

2.Museums — at a museum, you typically cannot bring in outside food and drinks, forcing you to pay exorbitant prices for food and merchandise. 

3.Sports stadiums — as with theme parks, you’re going to pay a hefty fee to buy food, drinks, and merchandise.

Non Captive Market :

The customers have a choice of where to eat. The type of restaurant chosen may be a fine dining restaurant of a deluxe hotel,  stand-alone restaurant, coffee shop, fast food outlet, specialty restaurant, or a popular restaurant.

Example :

Reason for dining A birthday party, Valentine day, wedding anniversary, or business meeting

Food preference of customers The type of food they want to eat. For example, Chinese dishes, south Indian dishes, sandwiches, and so on.
