There is a need for the self checkout areas, but it shouldn't be at the expense of staff. The biggest problem is that supermarkets are under staffed, they usually have a minimum amount of checkouts open. They have staff doing multiple jobs at any one time. Nothing wrong with self checkout, especially for people who want to dive in and out (like me) These places should be unionised, that would be a start, more staff on duty and individuals dedicated to one job at a time instead of jumping between jobs.
