We apparently walked into a huge convention of serious geezers, each of whom believed he/she was the only person in the store. Does AARP offer shopping cart drivers training for seniors? Two hot dogs with kraut and sodas? We're out of kraut. Raspberry iced tea? So weak I went to the Coke. Deli mustard? All gone. We've shopped Costco from Hawaii to Virginia and never had an experience like this. So long, Sossaman. We'll be trying the San Tan store.
