Heres a question for you. What if you are Cert in CCR Trimix, but not OC Trimix, then should a shop fill your big tanks?
I tend to fill at home but on a trip away I drew the short straw and fetched the cylinders down to the shop for fills for twelve on the Saturday night because my truck's big. I was wondering the same thing so I asked the guy filling what cards he needed for the fills and he pointed to the sticker on the cash register.
He took VISA etc.
I didn't argue as I thought explanations might only complicate matters as I was buying some hypoxic mixes.
