2. Insistent Sister
You call the receptionist and explain that you don’t have a sister called Layla.
“That’s what I thought, but I showed her your insta and she insists.”
This suggests a friend, impersonating a sister. (Though, if you’re honest, you don’t really have any female friends who would go to such lengths to speak to you.)
“Well, I can’t leave my desk, so tell her I finish at 4:00. If she really wants to speak to me, I’ll see her then.”
100 minutes later, you go to leave. A girl approaches you at reception.
