Think its the feeling of being treated as a 'Ahmad' that
irritates you.
Actually, most pple with driving license will know that its not
nice (proper courtesy and manner) that they should not let the
driver to be alone in the front. So, the qns is are yr friends
drivers (or they seldom take private transport)? If not, try
explaining to them, i am sure they will understand.
My friend drives a van too, never encounter this problem cos all of
us know. Admit that at some time in life a few pple will tend to do
that, but then i explain to them and so far no1 really 'guai lan',
heh......if he/she is, think i will kick him/her out of the
car.
Well the bottomline is, i hate this too.
