Sales taxes are paid by the customer, not the merchant. The merchants are required to collect and report the taxes, their customers are the ones who pay.

In fact, in many states the merchant must explicitly charge the tax to the customer, he cannot legally just include the tax in the price he charges for the item.

Even at movie theaters? I've seen movies in many states, and never ran into one that charged tax on top of the ticket/concession price.
