>What if I can't drive all the way to an ad-free restaurant

Eating at a restaurant is a luxury. If you don't like the experience, don't go (or don't go back). You're free to make your own food with stuff you buy at the supermarket, and you'll most likely get something healthier and much lower-priced. The entire point of a restaurant is to pay more money, frequently a LOT more, for a combination of convenience, service, ambiance, and food that might not be so easy for you to make at home (e.g. pizza) due to skill or equipment limitations.

So at least the supermarket should be ad-free, right?

Most of the supermarket is essentially ad-space. Companies often negotiate quite hard for good eye-line shelf positions for their products.

That special offer Tesco has on Pepsi products? Tesco is probably making exactly the same markup on each sale and the saving is actually coming from a supply price deal they have arranged with Pepsi in exchange for their products getting extra shelf space and end-isle displays.

High-shelf space (too high for customers to safely reach, so otherwise empty or used to store boxes of product to open when it is time to replace sold stock on lower shelves) often has advertising hoardings for products on other isles these days, again this is effectively paid ad space for the suppliers. If no external supplier is currently paying for it, the space is used to advertise own-brand ranges.
