WCMO is the forced (or attempted forced) use of online services or self-serve machines. Human interaction, even if only transactional, is important for social and emotional health. For some, the exercise of getting moving to go to Australia Post, motor registries, etc, is motivating for physical health. I also appreciate people being kept in customer-facing roles which, for many industries, becomes the first experience of employment for young people. If a queue has formed it is not the fault of the customer that the business is not properly staffed. My local supermarket has removed the express 12 items or less lanes and expanded the self-serve machines. If the staffed checkouts have too long queues, I just go to the service desk and politely give them the choice: serve me or be left with a basket of products to reshelve. I always explain why and have provided on-line feedback.
