Every time the minimum wage issue comes up, throngs of FReepers will point out (and rightly so) that minimum wage, entry level jobs are not meant to be career choices, but places for younger people entering the workforce to develop technical and interpersonal skills, work ethics, and an understanding of the value of their labor.
This is a great position when debating the issue of a minimum wage, but I think the test of how deeply one embraces that belief is how one may deal with an entry level, minimum wage employee.
As a customer of a business, it's not my job, nor my responsibility to train that business's employees. As a conservative, a Christian and a human being, it is my responsibility to treat them with a certain degree of respect and dignity. If, in my interaction with an entry level employee, I can coach or mentor them and make them a better employee (and they are receptive to it), I will avail myself of that opportunity. I'm not saying I'm going to stop my day and conduct a one hour business class for them, but I will give a generous tip where warranted (and more importantly let them know why). If I have a dispute over a product or service, I will rationally and politely present my case to them and engage them as to what they think the best course to resolution would be and what they would do if they were in my position.
If circumstances allow, I would very much rather get to the point where the employee says, "Let me check with my manager," or, "Would you like to talk to my manager," than for me to demand to speak to a manager.
Great,... but go read of the very typical encounter with a fast-food worker.
