Strangely, I rarely notice honking horns in New York. Guess I've just become to inured to it. Oh, occasionally I will hear them but it seems like it's far less than it was in the 1960s,where it seemed to be a raging cacophony, especially in areas of midtown.
As far as horn honking, since I don't drive, I don't honk...my contribution to reducing noise polution.
Regarding food, I learned a long time ago that it is unwise to ever send it back. No telling who is back there. It's not just the chef either, the waiter/waitress may be annoyed having to bring it back and forth when they were hoping to get to another table. Delaying for tending to this, means a longer wait for another customer which in turn can lead to a lower tip.
Probably quite rare it happening, however, I'd not rule it out entirely and would rather not take the risk. For me, if the place cannot get it right, I just will not return and will advise others of the issues encountered.
