I remember checking out and paying what I bough + tax.
Then abought 4-6 years ago, I started getting told I’d have to pay an extra 3% for the CC transaction fee. I left Mtn Dews and Gas Pumps siting out for everyone and their mamma to see.
I have a hunch you did the same.
That extra 3%… eventually I stopped getting asked to pay it. We did it together, but most impirtantly… YOU DID IT.
