#2: Don't walk this way and that

For God's sake, please walk a semi-straight line when people are behind you. Here I am, just trying to get across the skybridge to the parking garage--where I'll no doubt end up stuck behind someone going .002 miles per hour, terrified to make that perilous turn down to Floor 2--and just when I try to dart to my left and pass your slow ass, you amble over just enough to keep me from getting around you. Find a straight thread in the carpet or fall down on all fours and grope your way along one wall, but move it!
