I worked at McDonald's in high school and they've clearly revised the restaurants a lot since then, but they still have this mindset. I forget what they call it now, but the middle of any walkway is essentially a "fast lane" and nobody is allowed to stand there. It's one of those things that seems obvious once you hear it, but few people do it elsewhere. I wish everywhere operated like this... malls, airports, etc. If everyone who is stopped just moved to the sides then everyone in the middle could go so much faster.
