I turned off that runway about as carefully as if I'd got a rattlesnake asleep in my lap. I crawled along the taxiways cursing every lousy contractor who'd ever left a concrete ripple in any of them, and I could hear Yvonne and another attendant in the front jump seats giggling at each other, even with the cockpit door closed. Oh yeah, and the guy in the ramp tower is telling me to get the lead out. So screw him as well. Then I saw our ramp agent up ahead of us, waving his flashlight to bring us alongside the concourse.
