While working for Beaver Lumber one hectic Saturday afternoon my next customer in line was a seemingly nice woman who asked for "a sheet of plywood". Any logical response would be " what kind of plywood are you looking for ma'am" To which she replied" My husband told me to come and see you to get another sheet of plywood because he was going to be one sheet short to finish." SCTR.. "Well ma'am I have 1/4" to 1" thickness' in oak, birch, spruce,G1S(good one side)spruce, fir, G1S fir mahogany, cedar...etc. Ma'am "My husband told me to come and see you to get another sheet of plywood because he was going to be one sheet short to finish. I am not to come home without another sheet of plywood" After 10 minutes of discussion it wasn't possible to call her husband he was outside in the garage, the kids weren't home and she drove 40mins from out of town. She demanded a sheet of plywood right now. So I sold her an $85 sheet of G1S Oak. next time come back with a clue!!
