I went to AOAustin with my tank, no problem. But going back home was another story.
I told the turd boy manager what I had, and he said I could not bring it. "You can't bring CO2 cartridges." I told him it wasn't a CO2 cartridge, but an empty compressed air tank. He goes off telling me how it's against the law, how he taught a class and thus 'he should know' and other BS.
I explained to him that I could demonstrate the tank being empty. He said it doesn't have gauges so he can't tell. I showed him the gauges displaying 0 psi. I turned the valve on and off, explaining how it would be venting air if there was any in it.
There's been some confusion, so I'm not sure if my tank has been confiscated or not - I have different information. Gonna have to do some paper work and make phone calls to fix this.
Makes me mad... there's more pressure in this guy's colon than there was in my tank. Grr!
