Translation of ophthalmologist in German

One hour later people were starting to leave and we did not exactly understand why. We took another drink and I paid the bar man cash. Later it turned out that the change he gave me would be fake money.
At 6 am in the morning we got up and walked to the Tamarin cafe, where we were picked up an hour later. By the way the bus driver rode we could tell that our travel agency was more professional.
Than we took a cab to the actual border crossing. In the cab we took gave a ride to another tourist and with some scary Peruvian guy, who had a bag full of faked CDs. He didn't seem too nice and had many scarves.
