It's a different story in a gas station parking lot with just your space saver jack. Personally I'll always prefer working from above a removed wheel where I have more mechanical advantage and can avoid laying on the ground.

Sometimes you do get lucky on the fronts though, if the puncture is near the outside edge. Especially if your vehicle has a lot of caster presenting more of the wear surface at full lock.

But either way, we're deep in the realm of "sounds too much like manual labor to me" for someone drawing the line at attaching a can of green slime to the valve stem and pressing down the button. Wheel on or off, it ain't happening.
