I personally don't like self-checkout (really don't like it, if you want me to do work in your establishment either pay me or at least give me an employee discount) some people do and I think this idea is too simplistic an approach to the issue. Can you imagine a huge Walmart, where a lot of people prefer using the dozen or so self-checkout lines, being limited to only two of those lines? There needs to be a mix where both types of preferences can be catered to. I think a better approach would be to ensure there is a non-self-checkout option with maybe some language about line length...

Personally I love the lifetime option, and it was a major selling point for me (it is much easier for me to justify a one-time splurge of $200 instead of adding another monthly outlay). What convinced the business-side that that was a good idea?
