Have to laugh really.
When i started my new job they sent me to one of our sites is Wisbech .
The maintenance man there was also quite new.
I was there for training, a florescent ceiling light needed a new bulb.
Ahh says the guy ,we have a load in the cupboard.
After trying about 6 new tubes we realize the old guy had simply put all the used tubes in the boxes of new ones..
Ive now got a used bulb ,battery electricle collect service set up for disposal.
