English is a tricky language, and in my reading of GP i was incredulous at the word "never", especially since service workers can be in bad moods or stressed and that becomes, to you (or me, or GP), external stressors.
Oh, I think you are right there. I can't think of any times I've been rude to a worker off the top of my head, but I'm sure if we went over my life with a thin tooth comb we could find some instances. So it should be unusual that for an otherwise friendly candidate, this just happens to be the day when they have an unfortunate interaction.
