There’s a buzz at the venerable Loblaws store at 301 Moore Ave where staff is wondering about the mystery project at some of the older stores where the checkout aisles have been reduced by one. At Moore Ave. that means seven not eight. “They want to use the space for something but nobody knows,” said a whisperer. As of Saturday evening, aisle eight (the former fast lane) was stacked with potted plants and the “12 items or less” aisle had moved to number seven.
