At first, we hired our friend, Erin Lee, to photograph 50 people (also our friends), and cartoonify them to be customers in our Bartender Drill App. However, when we were done building the interface, we realized they didn't matched the theme. So we've replaced them with actual cartoons.
These cartoon characters are your customers in drills which intensify as you progress. Conversations fade away, and you have to deal with up to 4 simultaneous characters ordering a multitude of drinks. This allows instructors the freedom and flexibility to provide feedback and train individually.
