It was his first time out clubbing after working here for a decade.
But he will remember the occasion at the end of 2012 for all the wrong reasons.
A woman slapped him and accused him of molesting her. He ended up getting arrested and charged with the offence.
After an emotionally draining year, he was acquitted on March 19 after a four-day trial last October.
The 40-year-old Myanmar national, who declined to be named, told The New Paper last Thursday he had gone to the Pump Room in Clarke Quay on Dec 2, 2012.
Two colleagues who were going home to Myanmar for good had persuaded him to join them after their company's annual dinner and dance.
After drinking a glass of whiskey-coke, he joined his friends on the crowded dance floor.
The technician, who earns about $2,000, said: "I drank only three glasses of beer at the company's event. I was not tipsy."
He said he was dancing beside a tall Caucasian man when a woman cut in between them.
He said: "She stood on my left. I don't remember what she looked like but she was quite plump and in her 20s.
"They started hugging and kissing. His hands were all over her. I looked away."
Court papers said the woman had just met the Caucasian man that night.
Suddenly, the woman turned towards the Myanmar national and slapped him two or three times on the face.
Shocked, he asked her why she had done that and she accused him of touching her.
