Why does everyone assume I'm rich or have a huge budget

Every time I call someone looking for parts and I say I'm building a pro-touring car it seems like they assume I am loaded or working out of someone else's check book. I can hear it in their voices over the phone, the tone of voice changes from a why are you bothering me by calling to how can I serve you my master. I don't have a huge budget as a matter of fact I basically ***** myself to buy parts for my car. Is it the word pro-touring?
