but can appeal for such cases or not? i'm just wondering, all
these inspections rely on human.... so human errors might occur
sometimes.... so if we use dat to say dat our coupons has got no
marks, then who will get the benefit of the doubt? or they will
have other ways to record, e.g. the coupon ticket no. so that you
have to produce the coupon to appeal?
tis question has been in my head for a while... so if somebody can
advise me, i'll appreciate it very much.....
