The 'true explanation' is even simpler -- your impression is incorrect. <grin>

In the U.S., Visa/Mastercard/Amex/Discover/Diners Club contracts all 
expressly forbid charging extra for a card transaction.  Using language
that applies only to a 'premium' or 'surcharge' applied to card transactions.

They do *NOT* forbid giving a discount for cash payment.  They do not state
it =is= acceptable -- they are simply silent on the subject, which means that
it is not proscribed.

The logic:  The card purchaser must be allowed to buy at the 'advertised'
price.  Prohibiting discounts gets into a 'restraint of trade' issue.

Gas stations that offer a 'discount for cash' do not give that discount 
even for 'house brand' cards -- which do not have any fees that are 
payable to the issuer.
