What an odd reaction to this article.

Do you believe there is some sort of moral or ethical obligation that restaurants must operate at the same margin for every transaction? Should liquor prices be reduced to meet the margin of the steak entree?

Those "air-conditioned dining areas" help create the overall economics available to supply you takeout; few restaurants could sustainably survive on takeout alone. Takeout orders also either cannot buy higher-margin items (alcohol) or typically do not (dessert) so it's not like the are a strictly equal value proposition.

Takeout and dine-in are not two separate business, they both operate together.
