It is not a violation. Sutter, ICCDS, Second-to-None, New Image (are they still around?) are some that come right to mind. My daughter, niece and now my nephew have all done pretty good with alcohol/tobacco compliance. My niece used to do really well with Measure Consumer Perceptives but I am not sure if they still are around and whether or not they do those shops anymore. I used to schedule the shops and loved it when I got someone that wanted to do a lot of them regularly. They are a great way for younger adults to make some real money.
CanadaMommy do your research. Generalizations are fine. Who shops hotels, who shops grocery stores, who shops compliance are all fine without mentioning the client.
