Yesterday we were using this study room in the library for more than 2 hours since nobody's coming to claim their turn.
Suddenly 2 guys came, standing right in front of the door looking at me.
Then I asked,
"did you guys booked this room?"
They looked puzzled and said,
"sorry? you have to book this room?"
"no, I mean did you booked this room?" I repeat.
They both were so blurred and then replied,
"oh no no, we are the technicians."
Oh ok... *embarrassed*
