Translation of atomic 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 decided to walk back and explore the city on foot. It was hard to cross the streets as there was an endless flow of motorcycles and bikes. One needed to just enter the street and cross it.
We shivered, sweat and vomited the entire night. In addition we had the worst room in the worst hotel in town: Hostal Resbalosa.
