What I would be curious to know is how they plan to manage the uptime. Pretty sure the average line person at Chipotle won’t be able to troubleshoot the PLC should it fail.
It’s basically a very repetitive task, so it does make sense to automate. Except what happens if the automation fails in the middle of a lunch rush. Hell, people can’t calculate the change you are owed back in their heads anymore.
Even when they have a register/computer calculating the change, many times they screw up that transaction, too. Give a clerk a $10 bill and a $1 bill for a $5.95 order, and many will, after looking at the two bills for a bit, hand you back the $1 bill, key in the $10 bill like they are smarter than you, and give you the additional $4.25 in change. Some who manage to actually key in $11 are surprised at the outcome.
