That is wrong, like when (disclaimer: I am a New Orleanian) the former owner of the Popeyes corp would have his power racing boat as a carnival float, bedecked with former strippers turned trophy wives of friends, and would throw doubloons (like big coins) that doubled as coupons. So you were a kid scrambling for beads and such, getting mashed knuckles, only to see you get $1 off a 3 piece. Made one feel cheated. Another year a krewe (parade organization) in the suburbs was having financial problems and took the sponsorship of a plumbing company. Note: krewes don't do that. This one did. Everyone who went seemed to have the same reaction to catching cups and other stuff covered in plumbing ads. Just felt dirty.
I see one tiny exception on my anti-advertising stance. I am considering giving out business cards for my walkthrough's blog to each small group that attends it next year... so they can share it or maybe relive some of the scenes they liked. But this is a nonprofit setup, so I don't see it as being rude like Avon, Pampered Chef, Adam & Eve, etc...
