You had done the right thing by calling & asking them to return it. It would be considered rude if you refused to accept it now. You now may spend the money and buy them a nifty gift as a nice gesture. Not that I am miss manners or Dear Abby or something but I no i would be put off a little if i tried to be generous to someone & they kept refusing to accept my gift -money or whatever. just return the favor somehow!

Good luck

p.s. - came back myself from Neah on Tuesday -had about a 6:1 ratio native & lost as many fish as I successfully hooked 7 brought alongside -looks to be a good summer!
