Back in the day, I worked part-time at a movie theater - 10 hours a week doing administrative stuff. Our theater had a reciprocal relationship with other movie theaters in town, so their employees could see movies at our theater for free, and vice versa. The manager would just call the other theater and say, "Two tickets for the 7:00 screening of Blankeky Blank 3. The name is begood." And then my hubby and I would go to the theater, give my name, sign a tracking sheet, and see a free movie!
