Sleeping on Eurostar....idiots

There are often people who try to sleep on the Eurostar for the few hours they are on it. Its the people who try to lay on top of each other that are REALLY annoying. Its already small in economy and no space to move past, but there are those idiots who hang their feet outside into the walkway preventing you from passing, and when you do smack into them they will always jump up and look at you as if your in the wrong!
WTF!? How else can we pass!? The Eurstar staff pass through the coaches enough times, why dont they say something to these idiots!? Keep your damn feet inside your little seating area! I get it there isnt enough space sometimes but at least leave the hallway free for people to pass, idiots. (you know who you are)
