speaking about awkward moments, there was once for an appointment I went up the apartment after a long anxious walk around because it was a complicated direction up (i.e different lift from different lift lobbies). There were many people living there at the common areas too.
At approach towards the unit, thought to myself "heng ar finally reached"... and the door crept open and looking at me was... ANOTHER GUY
The ML I visited was opening to let another bro out at the same time for me to go in... "wa biang no staggered access..." FAINTS. Lucky the other bro is a stranger's face ha ha.
