They give you a token or a code to activate the air compressor; I have always been provided with either the token or the code when I asked for it, whether I purchased gas or not; complaints, when appropriate, may be filed using an online form. The water is fit for topping off your radiator; drink it at your own peril. In the few times that I have charged my EV since I got it a few weeks ago, the chargers were located in supermarket or shopping mall parking lots, not at "service stations," so they had no air pumps.

For what it is worth, I have never, ever been charged for fancy ice cubes, but then, except for happy hour, I can't remember the last time that I saw a mixed drink or a cocktail listed on a menu for less than $10.

Edited to add: The results of a quick Google search show that Connecticut and New York have similar laws.
