True story

I go to the same Starbucks every weekday. It's not like I have a choice - it's the closest coffeeshop. When I was in London I rarely went to Starbucks because I could get excellent coffee from Caffe Nero. Unfortunately that chain hasn't arrived in Hong Kong yet. Now all the staff at Starbucks recognise me and order for me a short skinny cappuccino.

It was while I was waiting with my friend L. for the coffee that one of the girls there struck up a conversation with me. I think everyone there is friendly with me because I am a target to practice English with.
"What does 'kamsahamnida' mean? Does it mean 'goodbye'?" she asked. Pretty much everyone there either knows or guesses that I am Korean. I definitely go there too much.
"It means 'thank you'," I said, "How do you know Korean?"
Actually, I had no interest in finding out how she knows some Korean, but in such situations it is polite to ask. And the girl was waiting for the chance to explain, I could tell.
"I was an escort," she said. My friend L. started to quietly crack up behind me, but I kept a straight face.
"Really?" I said.
"Do you know what is an escort?" she asked.
"No. What do you mean by that?" I asked back.
"I have visitors from Korea and I show them Hong Kong," she said.
"Oh, you mean you were a guide," I said, very relieved. L. was still stifling her giggles.
"Yes, yes, guide. I was a guide," the girl said.
"Oh well, good for you," I said as I took away the coffee and waved goodbye.
