Debit card machine. Get into the habit of punching in your debit card pin with a knuckle instead of a fingertip. Community pens. Whether at work or signing a credit card receipt at a store, never pick up a public pen because they’re covered with other people’s germs. Shaking hands. People are more germ-conscious these days so avoiding a handshake is not as rude as once thought, especially during flu season. Cellphones, tablets. Get into the habit of wiping your phone down with a disinfecting wipe to cut down on spreading germs. Gas pump. Drivers must get gas no matter what, sick or not. Protect yourself at the pump, grab a paper towel by the pump before picking up the gas nozzle.
