I'll take umbridge to that but im not defending all of us!
We'll grease what little kit we have regularly. We ran out of cartridges a month or so back and got a box last week. Got the apprentice to grease everything up and went through 3 cartridges!
The best bit was he's learnt to change them himself now so I let him get on with it.
I use up to 15 a week if I work 6 days.
