How do I withdraw money from a localcoin ATM?

Could you please elaborate on the process of withdrawing money from a LocalCoin ATM? As a potential user, I'm curious about the steps involved. Would I need to have a pre-existing account with LocalCoin? Or is it a straightforward process where I can simply walk up to the ATM, enter my cryptocurrency wallet details, and withdraw cash? Additionally, are there any fees associated with the withdrawal? And how secure is the process from a privacy and security standpoint? Thank you for your assistance in clarifying this matter.
