Not really, can deal with bills, crap, rip offs, but mechanics/plumbers/builders taking the p!ss because it is a protected rancid culture in the UK really p!sses me off.
Some garage did the same to me with my car (FIAT) a few years ago. Just started changing parts one by one to see what the problem was while charging me through the nose each time. Took it to another garage - they did the same. Third garage fixed it in 30 minutes for £50 and said all the previous works were unnecessary.
Disgusting humans. 1 down from pedos.
Rip off Britain.
