tell them that you'll be testing it on the fly and that if you make it back for a refill it passed with flying colors

I would think there would be a sticker on it from the testing agency or from the factory.

Plus like Rev said you will be back and thinking you will soon become there best customer ..............

I can see it now, fill it up the moment they open .... bench all day and rush back for a refill before they close so you can bench all night ...................LOL

Dude that is awesome! I would tell him that you purchased it from a company that tests and resells them....if they even ask.
