Car having it's mot today. Asked garage to call me and discuss any work needed/cost etc. DH is in work I have day off so more reasonble for them to have my number. Just got a call from the garage 
The mechanic told me car had failed due to "fbghirhtfga" (he didn't actually say that but he might as well have
). I said "could you explain what that means?" . He replies "Well you haven't passed your MOT love" No shit sherlock. I had to ask him a further 3 times to explain what exactly the fault was,cue jokes about dumb blondes 
I took great pleasure in pointing out to him that this dumb woman was the one paying him and will be thanking him for his piss poor service when I pick up said vehicle and pointing out that I will be taking my vehicle and money elsewhere in future.......and breathe.
