I work on photocopiers. Some people will lie to dispatch to get me out faster.
I can always tell you're lying 100% of the time. The copier tells me what happened, and I can remote into the copier before I even show up (which is helpful because I can bring parts I might need). But I'll never say anything. I just want the customer to be happy.
Edit: I'm talking about office and light production copiers.
Don't I know it.
Part of my job involves out main guys checking out buildings to assess potential danger if there's damage or whatever.
If a member of the public calls something in that isn't something relating to new construction work, it's always perfectly fine, they just don't like their neighbours or, usually, are racists who don't like that non-white folk are building.
Can't explain it but they're always lying and it's so clear. It's come to the point I genuinely ask "is it actually dangerous or are you complaining about the work?" They always come out with something about the safety of children and double down.
