I really don't know how frequent people use Bitcoin ATMs due to their very expensive markups, but why would you need a bitcoin ATM? I think bitcoin ATMs are best used when you're going to place them somewhere like in a subway, a mall, etc. But if you're going to sell some BTC on your own brick and mortar shop, why not just sell them directly? Manually? That way, you wouldn't even need to pay for the ATM itself, which can possibly be very costly.
Just my 2 satoshis.
