- Most San Diego Trust and Savings ATMs seem to have recently acquired a
- tinted brown plastic wall about 6 feet in front of the machine. It's
- not opaque, but I'm sure it makes reading a PIN from a distance using
- binoculars a lot harder. I suspect this is the idea.

- Nevertheless, I still make it a point to stand close to the machine
- and cover my hand whenever entering my PIN.
