Having to crawl through multiple menus to order is not that big of a deal for restaurants. They don’t value your time, they value their staff time (because they have to pay for it). There is probably very little ongoing cost to double the number of order kiosks while every additional human taking orders needs to be paid minimum wage. The restaurant owner watches with hate as their money slowly melts away while you decide if you want pickles, fried onions, and jalapenos on your burger.
