Restaurants aren't free from unfair practices, often they charge the same price for takeway as for dine in, whereas takeway should be cheaper not including delivery charges.
Costs including for facilities/rent/upkeep for dining areas shouldn't be added to remote orders. In some jurisdictions(esp in 3rd world), even are supposed to be different for takeaway and dining as orders made in air-conditioned dining areas are often taxed at a higher rate.
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.
Do you suggest they make the food on the street or is it ok with you that they rent a space somewhere? By the time you factor in the costs of the delivery service the cost to the restaurant is about equal. Unless you have experience in the industry I suggest you do the math first and then complain, assuming by then you still have something to complain about. Restaurants are nothing at all like the software industry.
