They call it invoices. Or you can talk to the people who sold you the shoes. Or they can check your shoe closet and go online and check for the price of the shoes. I know, I know it's hard to fathom but investigators know how to... you know investigate.
So you give your name when you buy things?
What color is the sky in your world?
Not in your local grocery store. Purchase a house or a Lamborghini most definitely. A purchase like that requires a deed.This deed requires a name or at the very least a company. Or like in the case of designer suits, those are easily traced and the clientele is usually exclusive enough to be traced to a person. Or in the case of a house renovation, again not usually a cash purchase and even when it is the contractor would demand invoices if for no other reason then assuring their ability to declare their income. And now I'm done with this game. I see no point in talking to someone who either has not an ounce of intellectual honesty, or is so dumb he doesn't grasp the most basic of concepts. Either way it's not what I consider productive or even fun.
