Sounds like you are easily offended...
The dude stops long enough to give you a card, shake your hand, and ask if you are enjoying the party, then proceeds to grab three drinks (presumably at least two are for clients/potential clients, whom he is taking care of), and he inadvertantly steps on your foot (I doubt it was deliberate, and it's quite possible he didn't notice).
Boo-fucking-hoo:
