I do.
I probably use my AC only 3 days a year.
I also rarely park in the sun and use the fan, and even wear shorts and a tank top at times.
Oh and I use the "Rule of 45" to save gas:
Over 45
MPH close the windows (to reduce drag) and turn the AC on.
Below 45 open the windows and turn the AC off.
Drag increases with speed.
I DO live and work near the beach though where the temps are more mild.
If he lives in one of the inland valleys then it is MUCH hotter and I'd use my AC there too.
He just asked for MPG advice.
I'm making a list of he can pick and chose from.
I don't bother with lean burn or pulse and glide.
I'm not willing to go through what I see as too much trouble.
But to people who want to do it I say, "More power to ya." (or actually less

)
But I don't mind too much being a little warm in my car.
Everyone's different.
