Sometimes it's because of multipacks. We used to stock La Croix, back when there weren't dozens of flavors and knock off brands. We'd get a 24 pack of them at Sam's that had three flavors, six lemon, six orange, twelve lime. Over time the limes would accumulate until one day we had a stack of them from the floor to the ceiling of the supply closet. We made a joke out of it, sneaking lime ones into people's fridges, replacing their lemon or orange with them mid-drink, etc. Our company was small enough that it never got hostile.
