How do they rip off old people? Aren't prices the same for everybody that walks in?
Besides, I'm sure most people would rather have a grocery store, even one that is supposedly "overpriced and filthy" than another bank branch.
What all these damn banks should do is take a lesson from what supermarkets around the country do and that is to have a branch within the store.
We don't need an entire branch taking up the whole space within a building's ground floor like they do now. Most of that space is wasted anyway.
