You seem to be skipping the part of the grant request (free money) that they had a limit of 70% of the charger's cost. So even by asking for the max allowed, they still would be required to put up their own money. No business person I have ever talked to would leave free money on the table.

My original question was asking if they are were requesting less than the maximum allowed, and you quibbled with the premise, yet here you are suggesting that's exactly what they did. You're suggesting it was due to altruistic reasons. I just did the thought exercise of knowing people will assume you requested the max allowed, then do the math to come up with a price that's not correct just to F with people. Seems exactly like something Musk would do.
