I hardly ever attach my name to a review. However, this must be done. I had a paid reservation for City Winery last night and was looking to maneuver into an available space. Apparently, no one keeps records, because it was packed! When I started to try and squeeze into the last available slot, 2 white guys were standing there telling me I couldn't, because they paid and their friend was coming. Of course they were NOT employees of DT docks. When I informed these people I paid and was pulling in as was my right, he yelled, "What are you, stupid?" Still NO DT docks employee. I was almost into the slip when a person FINALLY appeared. Although he apologized profusely and helped me tie off in an opening slot away from those people, to my knowledge, he made no attempt to tell the other boat they had no right to tell me anything. Disorganized. It is a sad day for boaters of color because without mediation in these situations, OTHERS will always try to throw their weight around. My boat is just as big, but I should not be forced to use it to gain parity. Chicago, hire another docking contractor!!
