Who Says There’s No Free Lunch (and Prizes, Too)?
To stimulate turnout at Broker Opens, 
Realtors will often offer a prize of some sort.
So, I’ve seen Twins tickets, gift certificates, restaurant coupons etc. given to whomever lucky Realtor had their business card plucked from the bowl.
The (occasional) caveat: some Realtors only give away the prize if a minimum number of Realtors show up (usually 10).
As long as that’s clear . . . sounds fine to me.
P.S.: I will confess — once in a great while — to choosing which Broker open(s) to attend in part based on the food being served.
But I can’t recall ever going to an open just to put my business card in a drawing.
