MovieWatcher
Sidenote to the two movie-centric posts prior to this one: With the Loews-AMC merger, AMC's MovieWatcher customer loyalty program arrived in New York City for the first time. I had a MovieWatcher account in high school, and not unlike my Blockbuster membership I held onto my card for years. So when AMC appeared in my neighborhood, I went digging into my old wallets, found my card, and tried it—online, no less. And what do you know! My account is valid and I'm still in the system.
The account balance was empty, but I felt remembered, and I got a good chuckle out of my card's longevity. I now use it every time I go to the movies and am once again partial to AMC theaters in my area.
Customers are as easily sated as they are angered. May as well aim high.
