Someone - a male, Indian-looking foreigner - approached me to ask for directions. He wanted to buy a SIM card.
After 5 minutes of mildly exasperated explanation, I decided to walk him to Cheers. On the way, I tried to be friendly:
"Wow, that's cool. What are you here for?"
"Oh, I'm here for academic purposes."
"Great, are you studying for your undergraduate or Masters?"
"Erm, actually, I've a Doctorate. I'm here on a research fellowship."
An awkward silence...
