Crisp is the cashier at Pinelli's Bakery located inside the General Atomics Galleria.
Crisp will continuously call out numbers ranging from 12 to 20, where at 20 he will start over again with a sigh and a brief statement of disappointment. None of the numbers the Sole Survivor can pick up inside or outside the bakery are in the range that Crisp is requesting.
