you are right but i have already said that a fail is a fail,never once asked him to pass it, so never put him a position of losing his job, going back to the start i had the car booked in but the near side washer was weak,all ok on sunday and know have found it to be a failed 1 way valve, all i said when i got there was it was not worth leaving as i knew it would fail, the guy at the garage said if i left it the mot guy would have a look and sort it , but have a word with him first, this is what i did, his answer was if it dont it the windscreen it will fail, what he could have said is turn the one jet on the drivers side to hit the near side screen leave the other jet on the drivers side and it will pass, that is what the guy at the garage poss meant , i have no issues with any garage or expect a car to pass that should not but as every think in life there are those who are willing to help and as i said job's worth why do i take it back there, as i said it is right by were i work drop of walk to work, 5 mins, but to be fair the next garage is 15 mins away but a lot more friendly so there it will go
