The "gas fee" for handing a banknote to a vendor is ... nil.
The "gas fee" for tapping a card/phone on an NFC payment pad is ... nil (you're probably tracked, ho-hum).
Crypto won't unseat classical until its "gas fees" go zero. At the very least to the payer.
There's no sales tax where you live? (which is entirely possible)

Merchants pay a credit card processing fee (2.9% + 30c per transaction) for each transaction. Looks and smells like a "gas fee" to me. It's much less than the ridiculous ETH gas fees, but credit cards cost money to operate. The fee is hidden so the naive consumer thinks they're not paying anything to use the credit card, but that's very much due to the actions of the credit card cartel, Visa/Mastercard.
Ask the vendors what their bank fees for handling cash deposits are and revise that statement.
