In the classical sense, no.
In the realistic sense, yes, as mentioned earlier, some advertising creates a negative reaction, and I promise myself not to buy a label.
As I get older, advertising gets less and less effective. I sued to use advertisements to know the fast food specials, but now I avoid them.
When shopping, if next to generic, I pick generic, unless previous experience tells me one is better htan the other, (like Best Foods mayonaise, I have tried quite a few different brands, but from now on it's Best Foods (Hellmans on the East coast I think).
I used ot be. The strangest thing was it was some kind of thought process, that everybody was watching what I was buying, and would judge me. Now when I see people's carts full of name brand items, I judge... "watches too much tv"
