And see it listed on your receipt ......
Or if the fee is tied to the individual sales. Of course that amount would be added to each sale, whether listed on the receipt or not. That would be a national sales tax.
If it’s like other industry promotions there is an amount due from each business. I don’t know how that amount is determined but I’ve never heard of it being tied to an individual sale.
Not that I agree with any of this stuff.
