Block paving course, are they having my trousers down?

OP if they had you fitting, refitting etc under testing bed conditions fine but on your situation you were used as slave Labour

I’d ask for a refund and have a read of this instead.

Fwiw, I’d say they’re definitely having your trousers down, even so I’ve got to quite admire them, just for their sheer cheek! 😉

Agreed pocketrocket, I’m on the phone in the morning getting my money back, bloody annoyed about the 2 days I’ve wasted though!

My next business is to set up a CrossFit gig, let’s call it builderFit. Charge 100quid a month for unlimited access to job sites where you get to carry materials, dig holes, mix cement.
No different to what CrossFit offer except something productive actually happens.
