I live in a block of flats, one of my neighbours knows that my car is fucked and had to be recovered from the hard shoulder on Friday.
The recovery guy said what he thought it was but I wanted to know for sure so I booked (and paid) for a mobile mechanic come out to have a butchers.
Me and DH go out to meet them and neighbour comes out instantly and starts asking the techs loads of questions about his own car! Obviously the mechanics don't know he's just a random neighbour so they answer but I can see they're thinking erm you paid for us to do one thing not diagnose multiple cars.
I turned to neighbour and said oh you are a nosy neighbour aren't you and he pretty much huffed off. But that's a rude thing to do right? Or is it just me.
