Description: Stand at urinals and make eye contact with person next to you. If they seem interested, motion them to an unoccupied stall - the handicapped stall is best. It's big enough and walls are long enough to stay hidden. But keep it discreet.
Or you can go into stall and wait for someone to enter in one of the stalls next to you. Tap your fit under the divider to see if they are interested.
