All jobs are worth something, can teach something if one wants. If he's slow on the register for example, he can get more practice. I once took a part-time job at much lower wages just so I could learn to do things I did not like in an office (filing, copying, data entry) and think about how necessary they are even though I don't like doing them. It can be so easy to think that we are destined for "better" things but as Mike Rowe showed on "Dirty Jobs" http://www.discovery.com/tv-shows/dirty-jobs/and his new show, somebody's got to do those jobs and they're very needed and sometimes quite lucrative (Filthy Riches) - http://channel.nationalgeographic.co...thy-riches-qa/

I loved my first job out of college working at my local Sears store in customer service; I could see and think about the whole corporation and what makes a business tick and what "departments" there are and what I might like to learn. A single store can give you an entire business education if you let it -- sales, accounting/finance, customer service, transportation, logistics, administration, marketing, research and development, security, etc.

One gets into a single store of a large chain group and get to know people in the store and you get an idea of what might interest you or not. I actually had an interview in my Sears after I'd been there for about a year with the security manager to be on the security team. There's all kinds of things to see and get into even from a simple job, if one has imagination and interest.
