Translation of cola in German

We spent the rest of our time, eating in good restaurants, shopping, walking around and going to bars at night. One night of these nights we went to eat dinner at the Palermo district.
Anyway, back on the boat station we tipped the father and left. The bus was already waiting although we were the first ones to arrive. We had to wait nearly one hour until everybody was back.
Instead, we gave him one of our Swiss chocolates as a gift so he would leave us alone. It worked: the boy went to the couple sitting next to us and tried to sell our Swiss chocolate for 2 Pesos.
