Forget hearing it on R4, I've heard it in real life! I shall decline from naming the actual Kiwi who started this confusion...

Some friends and and I were dropping off our Zildian friend at an airport a few weeks ago. This fella was going on and on about chicken so we moseyed upstairs to the restaurant. At which point, he looked down at the lower level, saw the check-in desk for the airline he was flying with, and wondered aloud why on earth we'd brought him upstairs when he needed to chicken. Some rather confused glances were exchanged before we figured out what was going on!!!!! This also made for a good bit of teasing for the rest of the afternoon...
