So, you're free to accept a bunch of free, expensive shit as long as you're able to rationalize it. You get to keep the free stuff and get wined and dined by the company you're covering as long as you say that you are unable to be swayed by money and gifts.
As long as the person giving the bribe doesn't explicitly ask for a particular outcome of said bribe, it's okay to accept bribes. I don't agree with you. I think you are accepting a bunch of free stuff and allowing yourself to influenced without any kind of accountability. No one is super-human, these items and expensive things are purchased with the sole intent to influence you and it has been proven to work.
If I still had my confirmed planning spreadsheets available I'd be happy to welcome a full audit of my freebie-buying ratio.
