I have
TWICE.
Very nice people. I had seen one person previous. Set up one (3 men-- Not all together, separate in the same room.)
A couple of days later...
Another call from the same person and another friend.
I was in a place of business at the time...
I did have someone close by, but I knew the person previous to that encounter.
I was very tired after needless to say.
It's not impossible, you just have to keep looking.
