This is only anecdata, but it happened to me more than once, that I typed in google the name of the restaurant and was couldn't find the real website of the restaurant over the fold, because the ads and the results are spammed with lieferando, and others. As a restaurant in a situation like this, you now have to compete for the search results, which isn't your main business. You want to sell pizza, not do SEO, or SEA. And then lieferando calls and tell you something like "hey, it's a shame that nobody is buying from you, right? Well, we can help for 10% of your revenue..."
