Instead of this in the wiki
"Only give in the vouchers at the return and make sure they only credit it at the return, just in case there's an accident you want the CC to consider it as a paid rental. (anyone with a clearer and more concise way of writing that please feel free..)"
I think it should be replaced with this
"Seeing as the CC only covers rentals paid in full by the CC (points/vouchers are not considered paid by the CC), one should only give the coupons at the end of the rental to Hertz just in case you need to make a claim Chsv"shlm. But if you do need to make a claim DO NOT MENTION THE COUPON and pay in full so that the CC won't have a reason not to pay for the damage."
