I am planning to throw a party at my place. The problem is that the bathroom door is quite difficult to close: the door knob is loose and hence I don't dare pulling it to close the door. Instead I need to pull the small latch under the knob quite vigorously. I can't lock the door either since the door is not correctly aligned with the wall (maybe the wood is a bit swollen because of the humidity).
I guess there are two problems: the loose knob and the door misalignment. However I don't have time to really fix either of them before my party. Needless to say that I don't want my friends to feel uncomfortable, especially since the bathroom is just next to the main room where most guests will be staying. I doubt people would appreciate leaving the door partially open when they use the bathroom!
What would be the easiest way to solve that unfortunate situation?
Edit about my situation: I'm renting the apartment so I can't really drill holes in the wall nor the door.
