I can't be the only person who instinctively trusts a product/brand less the more I see ads for it.
The biggest example is alcohol brands. It's almost guaranteed that the more advertising a brand does, the more middle-low quality is. (There will always be the ultra-cheap option with no marketing of course.)
It's mind boggling to me that in this modern interconnected era that this isn't obvious to everybody.
I was once on a Greyhound bus where a guy was loudly talking on his phone, but not on speaker. The issue was he was just repeatedly saying:
"Listen....... Listen..... Listen.... Listen... Lemme tell you.... Listen... Listen .... Listen lemme.... Lemme tell you .. listen"
For half an hour.
Finally a hero yelled out: "Listen! Lemme tell you to shut the fuck up!"
He said "lemme call you back later" hung up and shrunk down on his seat as the whole bus clapped.
