I used to be a bar manager 16 years ago and would often see the Anheuser-Busch marketing rep for our region out and about, and she would never fail to use her corporate credit card to buy me some free drinks. I liked that form of marketing.
I could have flown myself to Nashville every weekend. But they made me feel special with a plane ticket and a few bar bills.
I guess it's the difference between 'marketing' and 'sales'.
