Boring bas**rd here...
Brother labels on every cable, every 5m, and a laminated page with full description affixed to CU/DB...and, saddo that I am, each socket/fcu/outlet labelled with breaker number...
I really need a holiday!
Never mind, I did a plumbing job today for a friend, where I was called in to fit a shower enclosure because the tiles used were incredibly hard...and I mean they were impossibly hard! I bought a £30 diamond drill bit, and each hole took 20 minutes...
Wife said "Well, did you manage to drill Anne's holes?"
I let that one go...
But no, I was too busy fitting the shower!
