I tend not to do this and warn others not to as well.
The problem with gas-station air hoses is that they get dropped on the
ground a lot and get dirty, and then they blow that dirt into the valve
seal when you use the air hose on your bicycle, and dirt in the seal
will lead to slow leaks. You might not notice that with a car tire at 30
psi, or even a balloon-tire at 35 psi, but it can become obvious with a
1.3" wide bike tire that you want to keep at 100 PSI.


They also hold air better at high pressure, ....

I was not aware that this was any problem, at least as far as bicycles
are concerned. There's heavy equipment and aircraft tires with inflation
pressures of 100 to 200+ PSI and their schrader vales seem to hold up
just fine.
