Elgin, IL – With an assured grin and a positive head nod suggesting he has done this before, 17-year-old cashier Joe Blum is confident one plastic bag will hold two cartons of milk. “You got this Mrs. Seagle. You got this,” confirms Blum as his direct eye contact gives hope to his paying customer, 71-year-old Mrs. Ellen Seagle. “I’m so money with this. It’s all about leverage, torque, and grip. You hold the bag right in the center of the handles and stay balanced on your feet. One bag gets the job done. The customer is happy. The environment is happy.” At press time, Mrs. Seagle was on her way back to the store to buy two new cartons of milk.
