For now I have never used bitcoin to buy or exchange directly with people face to face because I for now I used to use bitcoin for cyberspace transactions do not have to meet directly by the seller.
It is unfortunate. I've done meet and greet with my bitcoin user community. and some of them sell goods and services onsite and I do face to face transactions with them. a bit awkward but it was very enjoyable. although you have to wait a little longer to get 1 confirmation first Lol
