I thought this was an obvious one. Can confirm: it is not. Standing right next to the carousel obstructs everyone else’s view of the conveyor belt so not only are they unable to see if their luggage is coming out, when it does they have to push past a sea of people to get their bag. Stand back, and when you see your bag make your way to the edge of the carousel. Simple and way less claustrophobic for everyone involved.
Do not stand right next to the carousel
