In my house is a dish drainer which has a caddy on the edge to hold cutlery in an upright position. It's quite deep, so only the tines of a fork or the bowl of a dessertspoon sticks out of the caddy if put into it tine- or bowl-side up.
Person A argues that cutlery should be placed in the caddy tine/bowl side down, because if they are pointing up, when someone in the house grabs them to put them away, they will touch that part of spoon or fork that goes into another person's mouth, possibly with unclean hands, thus spreading germs.
Person B argues that cutlery should be placed in the caddy tine/bowl side up, so that the water drains away from the part that goes into a person's mouth, and so that the tines and bowls are not touching the base of the caddy, which may be dirty. Also, all the photos online show the cutlery that way up (see pic) which proves it is right.
