Translation of paranoid 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.
We cursed our bus driver and tour guide and everybody knew that these people were not professional. After 2 hours we arrived at the destination. It was a little boat station on a riverbank.
In the end, the taxi dropped us also at their hotel (Hotel Monarca): Three stars, rooms available, hot water, a decent breakfast, free Internet and 2$ more expensive then our hostel.
