Regarding exhausting, here's a quote from a different blog post of theirs describing how to avoid surveillance in person purchases:

> I once took about 20 minutes at a Target checkout trying to get enough cash from the till to buy Christmas gifts for my kids and nephews. Then there was the time I held a bunch of kids' books at the counter at Barnes and Noble and drove around for 15 minutes until I found an ATM open on a Sunday evening in NJ. Getting cash out before a kid-related purchase is basically second nature to me now.
