Grumble

The only reason ORD works as well as it does is because they bend the rules, and everyone knows what to do. It's obvious when someone is in the mix whose not willing to do it the ORD way. Go listen to ground when a bank is pushing, they'll read off 15 clearances and once with taxi instructions and never unkey the mic, you miss yours or won't taxi until you've read it back, you'll never leave. I've never heard of anyone getting yelled at for screwing up their instructions (as long as you don't go on to a runway) but prepare for the wrath of God if you stop and screw up their flow.
