The DREADED-AIRPORT-SECURITY-BIN. More specifically, the DREADED-SHOES-IN-THE AIRPORT-SECURITY-BIN. It does not matter if they are yours or mine. The soles are coated in germs, not chocolate. And now, so too is your overstuffed plastic baggie filled with liquids. Soon after, the inside of your bag. Then you touch your mouth without washing your hands. Next thing I know you are sneezing next to me on an airplane:(
To save humanity, you may want to consider placing your shoes directly on the belt.
