1. The noise in a Mexico City market is annoying. Who wants to hear a “norteño trío,” a marimba from Veracruz or a romantic bolero when you can delight yourself hearing nice elevator muzak in the supermarket? The screams, jokes and pranks of the marchantes have nothing to do with the hollow peace of Walmart. You go shopping, not to party.
2. Who wants to eat tacos, gorditas, pambazos, flautas or barbacoa in a market when you can enjoy a hot dog or a pizza slice that has been on the counter for three weeks?
