OK, maybe. But again, did this bank policy change between 2004 and 2005 for most people? It's your last comment that's exactly the point. No one carries that much because no one wants to spend that much. So they pay with the credit card.
I think so.  The fellow working next to me said he has seen local news articles on the change in policy, and that it is widespread around here.  

And I should have noted that the money comes out of the same place, my account, with either credit or debit transactions.  The only difference is who pays the transaction fee.  

I did use a classic credit card for gas last year, when I was a self-employed builder.  I hated to do it, but I hadn't made any money yet.
