There's a section on the Bitcoin Wiki listing some mail providers who accept bitcoin, check the list out and maybe you'll find a better or cheaper site.

Here's a link.

Well the money would be yours anyways (if you own the machine). When purchasing the BTC at the ATM, you sell some of the Bitcoins you own to the person using the ATM. You can also re-buy the exact amount the person buys on an exchange with your own money. The money the person puts in the ATM becomes your money. Bitcoin has no central authority and doesn't know its price.

I think I understand you. If I do the answer is that he could just open the machine and take out his cash. But it would be HIS cash and HIS bitcoins inside. If this is like other BTC ATMs I have seen, the owner must fund the machine. Kinda like a gumball machine you own. You could just open it and steal the gumballs or the money, but it's all yours already.
So the owner of this low security model must place it on the counter top or somewhere else that can be monitored.

Still at the same point. Very unprofessional service.
