i disliked an ad in tv before 2000 and decided to not buy the deodorant stick then because of that. like 10 to 15 years later i accidently bought the product- long forgotten that this was the one with that bad ad and actually liked the product and bought it regulary for some time (then remembering how bad that ad was, but okay the product was good actually). that was until they decided to put more plastics into packaging as well as less content into it (same price for package) just to make it more costly for me thus more profitable for them, whilst producing more litter and destroying more resources just for profit. The higher price would not have been too bad, but creating more litter for more profit made me then search a better product. then found a bio product with all natural contents, very few plastic packaging and even less pricy.

That ad made me NOT buy it. So that was the worst ad i've ever seen in two ways: it reduced my willingness to buy their product to far below zero lasting for a decade and i did not even want to try the product that i later found to be actually good, so worst case for the vendor AND the customer.

However that product later also had the "best" Price raise (by less content) for me ever as that made me search and find the then newly existing even better and more natural, less pricy product of their competitor.

Maybe good CEOs are rare.
