They’d end up an incentive for “shadow work”, the work they push onto customers and incentivize by making it more inconvenient if you don’t.
For example, they push people to use self-checkout by closing all but one or two manned checkout stations.
And, of course, the teller would then refuse to help me. They just sent me home to download the app.
The job description of the bank teller had become: "Convince the customers that bank tellers don't deserve to have jobs."
