How do I buy Bitcoins safely face-to-face? I've made a contact via LocalBitcoins.com and am going to buy some coins with cash. The seller is not verified, but as we will meet, it sounds ok:


I show him the cash.
He transfers the Bitcoins.
We wait one block.
I give him the cash.


Is this safe enough or is there anything I should take care of? Any scams known?

He requested to use my mobile internet, though (will enable Wi-Fi hotspot on the smartphone).
Shamelessly summarized from this extensive guide on local transactions:


You want to meet in a sufficiently public location, such as a pub or mall, preferably one that has an open wifi.
If you have agreed on terms in beforehand, print out what you agreed upon and take it with you.
If you have not agreed on terms yet, be sure to check the current price of bitcoin during the meeting.
Wait for the transaction to complete and check if the right amount was paid. If the other person is willing to wait around for one additional block together that is a good sign.
Specify your expectations in advance: When and where to meet, what each person will have on hand to make the deal, how the price for the bitcoins will be calculated.
Consider taking a second person along for additional safety.
