Place a jar full of marbles in the employee break area and another empty jar next to it labeled “Great Service Jar.” Decide what value to give each marble—25 cents, 50 cents, or $1. Each time a team member does something extra to help a customer or another team member, that team member takes a marble and puts it in the Great Service Jar. At the end of the week, count the marbles in the Great Service Jar and ask team members how they want to spend this money—whether they want to save it for the next week or spend it immediately on a group lunch, movie passes, or a reward of their choice.
