Last Saturday I did a wedding at a venue I've never played at before. The wedding was great, the B&G were very happy, and the banquet manager was also impressed 
After the event was over and I had changed clothes and was loading up, the bartender offered me a cold Bud Lite. He wanted a bunch of my cards, and we had a chance to BS for awhile. He told me one thing in particular that is worth passing on to the newer guys here.
Out of all the DJs that come to their venue, I was the only one that has ever had a pre-printed itinerary for them and took the time to go over it with them before the event. Most DJs do nothing and one or two of the regulars will write it down on a piece of paper when pestered enough by the house staff, but giving them a copy of the itinerary and going over important things like what time the meal is scheduled to begin meant a lot to them.
