Easy to stay nice and clean doing 8-5 Mon to Friday in Gen Office. Not so easy working a 15 hr night shift in the shed up to your ears in hydraulic fluid and all the other good stuff trying to generate the jets for the programme. There were many times that I took over at 5pm from the offgoing day shift and handed back over to them at 8am the next morning, after having worked virtually non stop apart from a brew here and there.
It wasn't Prima Donna behaviour, it was too bloody tired to really care if the crease on my trousers wasn't razor sharp behaviour. Luckily, some of the more enlightened GD staff cut us some slack on that front.
