Don't expect customer service. I have been bringing my business to this place for over 5 years (multiple 5 lb CO2 tanks at a time) and when I brought back a tank that had been underfilled they refused to take responsibility for it and then refused to do business with me because the manager said he didn't like my attitude.

This is clearly not a place where the customer is always right. The customer is probably wrong here and if the customer doesn't agree then the customer is disposable. They literally told me that they wouldn't serve me. The only resolution they offered before that was - just pay for another fill.
