In my area there are two grocery chains across the street from one another.

One has a self checkout that lets you bag your items however you want, has a wireless scanner for scanning at your convenience, and just has one polite attendant monitoring to help with issues or enter birthdate for alcohol.

The other has one that screams at you about unidentified items in the bagging area if you so much as look in its direction, and cameras jammed in your face with a screen wrapped in white LEDs to make it obvious you're being recorded.

Guess where I prefer to shop :-)
