Terry is a nineteen year old who is working in a community setting. He does not like to complete cleaning tasks but it is an essential part of his job. He engages in behaviors like talking to coworkers, going to the bathroom, or saying he is sick in order to get out of cleaning. His job coach has started having Teddy select one of three types of drinks at Starbucks he wants to have when he finishes cleaning his assigned tasks. When Teddy finishes cleaning he gets a starbucks giftcard his mom has provided and gets a 5 minute break to go get a coffee. Which functional protocol have they implemented?
