Ahh, a classic case of the power of suggestion on the part of the story-teller. After having received $1.00 back from the delivery-type person, each of the New Brunswick orienteers has paid $9.00, thereby totalling $27.00. Of this amount, the non-orienteering, unscrupulous, downright dishonest delivery-type person kept $2.00. This effectively reduces the amount paid by the NB orienteers to $25.00, which is the amount that the registration person at the meet received from them. Essentially, the $2.00 amount must be subtracted from the $27.00, and not added to it.
