When I worked in NYC for a year, the local lunch eatery learned to anticipate my order. Sometimes, my food was ready by the time I got through the ordering line. The robots won't do this. Also, despite company demands to suggestive sell / upsell additional items with every order, actual employees learn that I want a specific order, made a specific way, and they eventually tone down the "hey, would you like to try some more of our yummy items?," which is better customer service.
Secondly, the place where they should be automating is the kitchen. It is the cooks (and the manager) who struggle with making my burger without pickles ... who'll often realize they added pickles, so they take them off, leaving the whole sandwich contaminated with the foul flavor of the unwanted ingredient. A robot wouldn't add unnecessary pickles.
During a rush, the human cooks slow down after a while, as they get tired. Robots don't get tired, so they can keep their throughput high.
"During a rush, the human cooks slow down after a while, as they get tired. Robots don't get tired, so they can keep their throughput high."
1) That depends on the duration of the "rush". I worked with kitchen crews that maintained their speed for hours. As did I in the various functions in the workspace: 18 hours shifts without a break and without a meal, running non stop... so no, I disagree with your statement about the "rush".
2) Yeah, take robots. Use them as line cooks or for dishwashing. And when you got a malfunction or some other maintenance issues with them, your whole operation breaks down for a day as you have no human substitutes to jump in and keep the operation going. Have such breakdowns two or three times and your company is out of business.
