Not wasting my time waiting in checkout lines so I can act like some kind of social martyr does indeed make me happy.

There’s also the fact that you can have three self checkout terminals in the space of a single cashier. Even if it takes you twice as long as a cashier to cash out, you’ll be spending 50% less time in line for every cashier that’s been replaced with self checkout.
Nowadays, I only use self checkout as well, because I can get through it in less than 30 seconds, almost never any lines.
