that's the stupidest thing....while you're right, there are hundreds of retail jobs that are all pretty much the same, you NEVER know what could come up, and you may be in a situation where you need to get a job and start working TODAY. it happened to me once, and I had places I could go back to and start working within 24 hours. don't burn bridges!!!
