I sat in a park in Taichung to have a rest. An older man came up and sat next to me. He said how much he liked the west and he liked looking at the banking cards we used. He wanted to look at mine. I showed him an old card I had. It was not a credit card. He carefully memorized all the numbers on it. Quite quickly really. I do not know how accurately.
He then told me that some women like to walk around the entrance to the park bi guessed he meant that there were prostitutes there.
I left the park.
