Remember that I had a plumber who wanted to charge 1200 EUR for a 2c part + labour?
I don't blame him, I'd do the same myself if I thought I would get away with it. He doubled down when I called him out and entered "cunt mode".
Best of luck to you, lad. You were called out and doubled down... you had the chance to take your bollocking, but you went all out. Fuck ya - there are other plumbers who don't pull the piss.
Per your last message... "👍"
