We just started using new RNAV departures, so that is most likely why Jimmy is getting confused on what runways to send people to.
Frankly I don't need to read back a ramp instruction unless I'm confused. There are some of the controllers that will not issue an instruction without first saying your call sign, then waiting on your to respond.

Grrrr, I'm here just spit it out.
I'll take Jimmy at his worse, over any of the others at their best. (Except for one mainline ramp guy, who even Jimmy looks up to.)
Things seem to have gotten better now that RPA is on the mainline side.
