alternately, u may wish to gate crash the medical checkup.
cos seriously do u think they will check 1 by 1 who is coming on
which given date? i remember that during my checkup they didn't
even check my name.
the booking system is more like something to count and limit the
no. of people coming for checkup each day. let say the system
limits 200 people to come on xxx date. if the count reaches 200, it
will say that particular date is fully booked.
think about it, out of these 200 people, do u think all of them
will come as scheduled? surely 1 or 2 will absence themselves for
whatever reasons.
so if u dare, u may choose a date same as your friends and go down
together. if really they check, i don't think they ask u to go
back. worst come to worst if they really don't let u in, just try
booking again loh. what can they do u? sign extras?
