Foreign and Familiar

Visiting Guatemala is strange for me. So much of it digs into deep set memories and yet so much of it is beyond my comprehension. The chaos of traffic and the clouds of dust both left and stirred by passing cars is not so much disturbing to me as it is comforting. Yet I struggle to understand the omnipresence of 'Western' fastfood chains, gas stations, and consumables of all types. How have these gained such popularity?
