No, the money is paying for the cost of operating excavators. This is not a charity, the CAH team is not going out with shovels, the men driving the excavators are not volunteers. You're paying them to dig a hole. When CAH runs out of money for hourly expenses of hole-digging, the digging stops. That's it.

You pay for N seconds of digging. That's the whole thing.

Thanks. I was too naive.

It's not a donation. You are literally giving them money to dig a hole.

Yes. You choose the charity yourself, send the money to it directly, and, most importantly, you leave the CAH completely out of it, because they don't care.
