Not a freebie in sight
I used to go to a few trade shows in the UK for various types of equipment, even as the guy who signed the purchase orders, I still never received better than the odd propelling pencil, something I have never used.
However, most of the exhibitors I already had a working relationship with, would pull out bottles of good scotch and offer me a snort, I always declined as a: I don't like scotch and b: I like to be able to remember what I have ordered and signed for. The upside was that I used to get good discounts for personal purchases that I needed for ahem, my side job.
Biting the hand that feeds IT
