Which state are you in? I have worked for Sentry and went right into fine dining after one fast food shop. They assigned me a total of 4 fine dining assignments after that. I do not work for them anymore because I find the long fine ding reports tedious. I shopped their mid range fine dining chain in the Boston area, felt the suburbs shops hang on the board awhile.
Now that I think of it, my first shop was fast food, and my second shop a fine dining lunch.
I believe the lunches are harder to fill. I also stopped the fine dining as I lost my shopping partner, and if you were in Boston area I may partner up with someone to teach them the ropes and be able to dine with someone else.
