That conflicts with a different cultural "fact" I have about US citizens. They love convenience (for example, "convenience stores") and willingly pay extra for it.
Middle levels have the money to burn and often prioritize time over money. Plus complaining about paying $3 for an apple at the gas station quickie mart is a rare and cheap conspicuous consumption opportunity for them. I only have about 2 hours "off" unallocated tonight and I'm not going to spend 1/4 of my time off today saving $2 on the cost of an apple by going out of my way to shop at the food store.
For poor people its a poor people budgeting thing. As per the previous recent discussions on HN, poor guy has $3 in pocket, gas station has $3 apple on shelf, he buys it because 1) he doesn't have $5 to buy a 5 pound bag from the supermarket 2) no idea when/if he'll ever have an extra $5 again to spend on an extra luxury like an apple 3) travel isn't free when you're poor so bus fare and hours spent taking public transit to the store and time spent not working means that $5 bag is more like $15 total systemic cost and thats a bit steep for a poor guy who just has a taste for an apple today?
Upper levels have their personal assistant / admin assistant buy the apple for them. Its all going to be expense-d and its a rounding error anyway and the admin assistant is in a hurry so fine here take this $3 convenience store apple and I need a receipt for that thanks.
And thats how we love our $3 convenience store apples. Despite most apple sales being in 5 pound bags at the supermarket of course.
In the suburbs convenience matters with things people buy regularly. You see this manifested as large convenience stores with gas bars and large drug stores that also sell sandwiches and ice cream. Small independent convenience stores tend to lose out to larger ones that have larger gas bars, cheaper gas and more options inside.
What's interesting is this trend seems to be reversing a little bit in clusters. Younger people are migrating back to the cities, and more developers in the suburbs are building apartment complexes with shops and restaurants mixed together, giving it the feel of living above a really nice mini mall. :)
The ultimate convenience store is attached to a gas station and has a drive-up window so you don't need to get out of your car.
While the ones with drive through windows are rare, I'd be hard pressed to think of a convenience store within a 30 mile radius that was not also a gas station. As far as I can recall, I only see c-stores that don't sell gas inside cities.
