Not Fleabay, some dealers seem to want to charge the "admin fee" for doing the paperwork; otoh, I notice on Autotrader, many dealer ads. say, "No admin fees".
I look as normal; when I find a car I like, I check whether the dealer wants to charge an "admin fee". If he does, I consider it part of the purchase price; if that makes that car more expensive than another I'm looking at, I tell the dealer either he doesn't charge the "admin fee" or I'll buy the cheaper car. All part of the negotiation.
