Nitrox fills

[jasondbaker]

I do not think the issue is shops that require you to remove the nitrox sticker before getting an air fill. The issue is shops that require the big fat nitrox sticker instead of a simple, disposable, contents sticker. This whole thing seems so simple.

A) You have a contents sticker but no O2 clean sticker = you can get premix up to 40%.

B) You have a contents sticker and O2 clean sticker = you can get premix/PP/ up to anything.

C) You have no contents sticker and no O2 sticker = standard air.

PSI guys, explain to us why this is not a legal, safe practice.
