I had a similar experience. I went to an open bar birthday party, where with a particular wristband you could get unlimited drinks. I ordered something simple, and tipped a dollar, came back once, and did the same thing. The next time I came over, the same bartender made a beeline for me and started pouring two drinks before I got all the way up to the bar. Another dollar. Now I had two drinks and only two hands, so I gave the second to a friend, and found myself with an order for four drinks from some friends who noticed my speed of service. Somehow she heard this, and had two of them mixed by the time I got back to her.
