ASIDE from my rant, when i see advice asked for here, i try to offer the best advice i can, because when it comes right down to it, there are a LOT of shops out there that will try to rake ya over the coals every time. i don't do that...which is why i'll probably always be poor....but at least i can sleep at night.
i worked for a shop(midas) that was top of the line on selling things that cars didn't need. i stayed there only long enough to get another job, then i was outta there.
yea mcboi.......old people, i never hesitate on doing little things like that for them. i'm too close to being one of em(48).

women i do it for too, but i make it a point to educate them as i do it. i explain how much air should be there, and show them how to read the gauge. and of course, show them how to put the air in.
and yes, it is somewhat annoying when i see a healthy young to middle aged male come up, and want/need help with air, when my overweight diabetic mother doesn't need as much help as some of these guys.
and yea shirly....some places still have free air, although those places are becoming fewer and farther between.
