On a recent episode of 'Ssul Jeon', the panel talked about the various types of fans. Heechul said, "It's fine if people come see us at places when we have makeup on and we're working. But they shouldn't intrude on our private likes. Sasaengs are not fans." He talked about the times when fans had come into the Super Junior dormitory to take photos of their underwear.
Kim Gu Ra pointed out that he noticed that idols never went to bathrooms at the urinals, but inside the stalls, and Heechul said that even in the stalls, there are fans who stand on the adjacent stalls' toilets to take photos, so they have to lean forward.
Park Ji Yoon also mentioned that EXO members had to take turns standing guard at bathroom entrances so no sasaeng fans could get in while they were taking care of business.
