The passage of the head rest will spread

This time you’ll have to help serving the hungry people. Go to the kitchen and start serving the soup as the customers come in. After you’ve served a few people, Haitian gangsters will storm in and start shooting everything. In this mission you’ll learn melee combat.

Try to take out the most dangerous enemy first. In this case, that would be the guy with a gun. Then finish the rest of the gangsters. Once the cutscene is over, the mission will be complete.
