I repeat: Are you so sure that they missed it, or did they close
one eye? Perhaps they talked to her and let her through anyway, she
could have had her reasons.
The probability of 2 security guards (1 at her MRT station and 1
at her destination stop) both closing one eye is rather low. BUT if
this was the case then I have nothing to say abt it since they did
spot her but were lenient. But the thing is both of us dunno wad
happened.
