A standard
disclaimer common on e.g.
American coupons. A full
disclaimer containing this line might read "
One time use only. Valid at participating GNC stores only. No cash value.
Void where
prohibited, taxed or
restricted by law. "(taken from a
Soy coupon).
The reason that disclaimers even
exist is that the
US uses the
British legal system, i.e. making
vague laws and then letting the
courts decide how they should be followed from case to case, as opposed to the
French legal system, where laws are meant to be so
clear that they can easily be
understood and followed.
