There's definitely a culture shock when you first move here and are figuring stuff out - How do you order food at a subway or a chipotle? (not a big deal anymore given the explosion of these restaurants in India in the last few years). Why is called Cilantro and not Corinander? How do I get a phone when I don't have any credit history at all? What is a turn-pike?
You probably know this, but in the US Cilantro is the leaves and Coriander is the seeds of the same plant. Possibly because only the leaves are used in Mexican cooking, and a huge amount of US cuisine these days originates from Mexico, or pretends to.
