Even if it's my AFT or a new provider that I see, I still put in a plain unseal envelope and I either leave it a night stand or some sort, were they can spot it. Before or the end of the session.
If you had read the previous post that had mentioned in the past or the self help guide, it's a terrible idea to hand them the cash or envelope directly, hand to hand. Even some providers has mention it in there ads. So it doesn't matter if it's a new provider or an ATF.
Posted By: fantastatt if it was your AFT why would you need an envelope. I only use an envelope when its my first time seeing the girl. After they have seen me and know me there is know problem just handing it to them.
