If it was one bad experience one time I might be more apt to agree with you. But this is the new normal. Good service is the exception, not the rule. It should be the reverse.
I had started a much longer comment than this going into loads of detail, but really, I don't care how much fast food service people make, I care about being responsible for the work you are being paid to do. When you take a job, the amount you will be paid, and the service you are meant to offer are laid out as part of the process. If people don't agree with it, they don't have to take that job. Provide good service consistently, and better opportunities will open up to you. Provide crappy service consistently and you'll be left with nowhere to go.
