Translation of etikettieren

A bystander who watched the entire scene all the time decided to help me. He was an older man, around seventy, but nonetheless he went to the oldest of these kids and slapped him. The boy was sixteen.
Now I needed to decide where to go next and I decided to use the information that the girl gave me. I went back into town to the central station and booked a night bus to a place called Palenque.
Anyway, i got bored pretty fast, drank a Coconut and orange juice mix and went on. I returned my bike at four before heading again to the beach. By coincidence I met the sister of a colleague of mine.
