at my work i deal with a lot of tradespeople such as builders, plumbers, electricians. i have come to classify them all as arrogant and self-indulgent pri*cks who think too highly of themselves because they are big and muscley and drive fancy utes. i now categorise all tradespeople as such and i dont even give the actual person a chance. am i wrong for thinking like this? why are tradespeople arrogant? are other people prejudice against them also? i think i am quite judgmental and that i stereotype people a lot.

i am a 22 y.o girl and i deal with tradespeople accounts in a wholesale store.
i know that i am stereotyping them ... but what are they thinking of me? probably something along the lines of here is a plain jane with brown hair and an average body. boring. nothing special. no need for me to be nice to her so il just treat her like a boring little administration worker. i am possibly well-wrong, but that is what i think they are thinking of me.
