I lost my bicycle key and gained a tea stall in the Ancient Town

I lost the key to my bicycle lock in the Ancient Town one June afternoon and stood there with my hands in my pockets for ten minutes. A woman at the tea stall opposite brought out a small hammer, a screwdriver and a chair, and the two of us fixed it together while the tea went cold. That was June. I have had tea at that stall most evenings since and I have never paid for the first cup. I have never paid for the second either. I think that is a different arrangement.
