I was at WaWa the other day and paid for sausage gravy and a couple of packs of cigarettes. I have a habit of having a couple of hundred dollars wadded up in my left pocket all the time. It seems to upset people and the cashier said something about it.
I said "You don't know anything about personal security. I keep my money in my left pocket and my gun in my right and a hand on each one".
The same can be said about computer data.
