If you don't remember, Mene is the moogle who allows you to play Chocobo Hot & Cold.
I've been replaying 9 over the last week or so and it really struck me how awful Mene is. His whole thing is "I want to help my friend (Choco the chocobo) become strong and be happy." Now obviously we all know that that ultimately means becoming a gold chocobo and reaching paradise, which is a noble conquest for Mene; to selflessly help his friend achieve paradise. However Mene's interpretation of that is to charge the first person he sees 60 gil a minute to help his friend dig up treasure. Surely if he really cared about helping Choco he would allow you free reign in the forest etc. to dig to your heart's content, thus being a greater help to Choco. The fact that he tries to make money off it is sickening. Especially so (relatively) soon after we had FF7 and the message against capitalist and corporate greed.
Then when you get to paradise and you find out that Choco is supposed to stay there, the first thing Mene says is "but Choco has more treasure to find." No thought for if Choco even wants to find these treasures now that he's achieved his life goal, just thinking about how profit can be made.
On top of all THAT, when playing Hot & Cold if you manage to dig up 8 treasures, Mene comes over and asks you to stop so you don't put him out of business! What business?! He's literally charging you to dig on an island in the clouds. It's not his land at all.
That, to me, implies that Mene is the one burying the treasures for you to find, all to fund his own lifestyle. You can further go into that when you consider the clues on the chocographs can, at times, be rather specific. You'll get hints like "I think there's a desert nearby" or "try going somewhere you don't usually go." The only way to have that kind of knowledge of the locations is if Mene himself is going out into the world, burying treasure, and then burying chocographs in the forest and lagoon for you to find, all so he can charge an unwitting traveller into "helping his friend."

Maybe Mene really did want Choco to become strong & happy, but to do that he had to go and hide all those Chocographs across the world, racking in quite a bit of gil in debt from his travels. He had to keep Choco's interest in mind as well, so buying & scattering the treasures would cost a bit more of gil, and if Choco reaches paradise before all those treasures are found it would be like throwing away gil for no reason 
60 gil doesn't seem like too much, after all Mene has to eat too (presumably?
