This happened this evening. If you've ever wondered what we're up to when we say 'sorry I was on the landline', then this is for you.

Me: "Humberside radar"
Manch: "Manchester East co-ordinator, level please, KLM XXXX"
Me: "Hmm *rummage*... I don't have a strip for a KLM XXXX"
Manch: "Huh?... Oh god, it's going to Teesside you pillock!"
Me: "Heheh. Yes, entirely my fault for not being Teesside."
Manch: "Sorry, not you, I was talking to this idiot beside me."
The poor chap was still getting abuse for it when they called for a level on the next inbound.
