People who have rolley luggage type bags are the worst

Look if you're going to the airport or whatever, fine, push it around. 

But now it's like people like to put down their rolley luggage (often backpacks or briefcases) and pull out the handle right in the midst of an oncoming crowd. Instead of carrying it like a normal person with hands and doing it on the side without a crowd of people behind you. 

They also walk so damn slow and you can't easily get around it because of the luggage they are trailing behind them 2 feet behind and to the side.
