Wasn't it P.T. Barnum who said, "There's a sucker born every minute"?

ABO - Hah! I only had one year of chemistry in college, but I do recall
that an element is an element is an element. Oxygen is oxygen.

Yep, welding supply shops can be tricky.

Once I was on a errand to pick up a refilled (large type) O2 bottle.
While I waited for my turn at the counter, I noticed a truck being
unloaded at the dock. It was loaded with green O2 bottles - none of
which showed the blue "Aviation Oxygen" sticker.

Since I couldn't see any Aviation Oxygen bottles, I told the
counterman I wouldn't be surprised if he couldn't fill my order. "No
problem", he said, "Watch". He opened a drawer, retrieved a sheet of
blue Aviation Oxygen stickers and slapped one on the nearest green
bottle. "Now, he said, "I can sell you an Aviation Oxygen bottle -
that will be $115." "How much would it be without the sticker?"
"$35", he said.

It's surprising how honest people can be at times.
