Let's say you go to a store and ask if they have a certain product. The clerk says "Sure, here it is". Is that worse than saying "Hmmm, I have to check in the warehouse first"?
But apart from that, clients usually appreciated getting their food about twice as fast as they would normally expect. As long as the quality is there, nothing is wrong with speed. And a restaurant is kind of a poor comparison, since cooking is always time dependent, while other goods can be ready for purchase at once.
I get it, sales and marketing are an essential part of doing business, you will not have a business if you can't sell anything. But it is an inherently evil practice, the whole goal is to coerce somebody into doing something they would not have other wise done. When kept to a moderate amount this is not a problem, the business sells things the customer gets things, everybody is happy. But sometime the marketing department can push thing to a very unhealthy level, psychological manipulation, dark patterns, obsessive tracking, etc.
Humans want things to operate at human speeds and computers are way faster than that.
But that's because you're interacting with a human and that sort of behavior from another human typically indicates a kind of hostility.
Interacting with software is nothing like interacting with a human, and doesn't trigger those human social cues.
