Always get the itemized list, babes. ALWAYS.
Not just for medical either. Ever got smacked with a huge ass fee for "damages" when you move out of an apartment that not just eats your security deposit but tries to take an arm and a leg as well.
Ask for the itemized list, you will be surprised how fast they come back with a "huh, that's weird, I can't seem to find where these damages are coming from" and let that shit go.
People WILL try to screw you on all kinds of routine and mundane shit. Don't let them.
