Hamid immediately went for the single cup solution but found that the triple cup with the walls were best for storing $1 and $5 bills. He immediately began putting his money and bills in the model, and informed me that the three containers for holding different coins were unnecessary since he deals mostly with quarters. The shorter cup size made it easier to see the change and pick up change. He began to revert to his old ways of placing bills on the shelf since there was no more room on the model for dollar bills. So I know I had to change the design, but I left the model with him.
