Because the customer didn’t pay the tariff, the business did - unless of course the business flat out added a “tariff surcharge” or something of the like to the total that the customer can see.
Increasing the cost of an item by the amount of the tariff is not the same as making the customer directly pay the tariff. The business was charged the tariff. They were invoiced and they paid it. The customer didn’t. The customer just bought an item at shelf price.

You’re just making shit up.
I’m saying that the business is the one who was invoiced for the tariff. The customer wasn’t. The business increased the price to cover their extra cost, probably even added some extra profit on top as well, but that still doesn’t mean the customer actually paid the tariff. They didn’t. The tariff is paid on import, not sale.
