One thing I have noticed throughout my life is that if I dress nicely and go somewhere I am treated differently than if I show up in shorts and a t-shirt. I'm the same person, but if people think you have money they treat you "preferentially".

I have had people treat me this way. I'm a fan of short and a simple shirt, and one time, someone I met on the street thought I was broke to the teeth and that was why I dressed that way. Of course it's not like I had money, but I wasn't as broke as they thought I was.

You're right, somehow people get preferential treatment because they think you dress well because you have money
