People who get stroppy and angry with me when I cant fix their car at the roadside.
Had a guy raring up at me the other month with a VW passat which had thrown a rod through the block, explained that there was nothing I could do to fix it and that I would recover him to the garage. He wasnt happy with that, got really angry and aggressive towards me and said that we're supposed to be able to fix everything! Told him to stop shouting at me or I would leave him where he was and be stranded. After a while, went to get in my van and drive off. Surprise surprise, his attitude soon changed!
I hate being a verbal punchbag just because the people i go to are having aproblem with the car and need to take it out on someone.
And being in the cold, shitty weather!
