Fast food is one of those cases where I'm completely happy to get their ads for a similar reason to the poster above. Youtube's non video ads too, though for a completely different reason (I get the oddest ads for spinal implants and petabyte storage arrays)
I have completely dissociated all correlation of a filling meal/nourishment with this brand.
Again, to me, Taco Bell is a marketing company with a new product-of-the-month every month whose products just happen to be something that you chew and swallow.
Everything there gives me watery diarrhea. Granted, I couldn't get enough of the Volcano Tacos when they were a thing (unless the sauce had been sitting out for hours, at which point it was disgusting; it was very easy to tell by taste how fresh it was), but on the occasion that I walk by a T.V., there's often a silly, attention-grabbing commercial for Taco Bell.
Improving my life? At best, sure, when I was a kid/teenager/broke college student. Kind of like toy commercials, I reckon.
