This is just my humble opinion on the matter but I would do neither. Also, are those the two choices you are looking at for a job? I have never worked at Taco Bell, but I have worked in fast-food. It is hard work standing on your feet all day and it does not pay well. I encounter CNAs in my profession, and they do all the grunt work in assisting RNs. Such as changing bedpans, taking BPs, bathing pts, etc.
