So today I bumped into news on allkpop
allkpop noted that::
A person had written, "I saw Kyuhyun who was traveling withTVXQs Changmin. He must have been in a big rush after drinking because he stopped the car and urinated on the street. They were polite boys who maintained their manners even though they were drunk. But they didn't tip. I was their designated driver."
Kyuhyun relayed his apologies, saying, "I was really in a rush. I'm sorry. In that area...." and trailed off, unable to think of an excuse."
