You can as well manually share the service needed by the requester, name of the requester and if possible the picture too.
Ensure the face of the reqester matches what is on their profile and ask who they're here for. Once the picture matches the face of the requester, verify the pin on their device with yours before proceeding.
Intuition goes before you, showing you the way so always trust your guts instinct but if there should be any doubt in your mind concerning the requester or the location of the requester, politely let the requester know and cancel the request immediately without having a second thought.
