Something I never understood

If you don't want to play the game, why even queue? So many times you get people queuing into games who will AFK automatically, admit that they're drunk and don't care, plan on losing, etc.

Instead of wasting the time of everyone else for 20-40 minutes, why not go sleep? Why not watch a movie? Why not do anything else except queue? It's frustrating going on a losing streak where you get shit luck and draw one or more of these people every game. Hell I would much rather just 4v5 than have to play a 5v5 with someone who admittedly doesn't care and dives the enemy tower 10 times by the 8 minute mark.
