I remember when I arrived in Bombay, India for my first overseas posting. The biggest "culture shock" I experienced wasn't moving from a developed country to a developing country; it was in seeing how suppliers delivered food.
A common sight while travelling through the congested, gridlocked (that is an understatment) streets of Bombay was to see eggs delivered by a kid on a bicycle. The bicycles used to deliver eggs would have this rack on the front and you would see flats of eggs stacked so high the kid could barely see above them, all the while these eggs are probably at a constant temperature of around 90 degrees farenheit as they sat in that natural incubator known as the Bombay heat and humidity.
At least they cooked quicker since they didn't have to be heated as much.
