Recognizing the stickers is another issue.
There's no requirement that any fill station accept any particular VIP or "O2 clean" sticker, so even if you go to the trouble of getting certified and doing your own tanks, you might not actually receive any benefit for your effort.
If I was the guy doing the fills and a tank came in with an inspection cert I didn't recognize, there's no way I'd fill it. Having a tank neck explode because the inspector missed a neck crack can ruin your whole day.

This is very true and is why it pays to get to know your local fill station operators. When traveling is it good to have to a copy of your cert in case someone questions you. And remember if you do inspections for friends that you are now opening yourself up to a potential liability.
