so its the next day I take the car in to get serviced

we do the small talk I re-introduce myself because
he has no recollection of ever meeting me or having
any conversation with me whatsoever.

we go and look at the muffler and he concludes that
I was in fact right about the muffler and had been truthful.

He talks to his welder guy and I find out they don't have
the welder machine because yesterday the guy decided to
take it home to weld a roll cage in his car.

so he tells me to come back in a week to get it fixed.

I was pissed.
