I think it does make a difference. When the parties are voted for before forming the coalition, you know exactly how many people supported them and their policies. Then the coalition is negotiated based on that. If you form the coalition first, then only the majorities inside the coalition matter for who has the most say, you have no way of knowing what’s important to the voters.
For what it’s worth, while there certainly are public bathrooms with stalls from floor to ceiling, the most common design does have gaps between the floor and the stall (at least here in Germany). Just not as big as the gaps in the US. You’d have to get uncomfortably close to the floor of a public bathroom to see anything. And no gaps between the door and the walls.
