Back in the day when I first started out hobbying there was no internet or it was still in it's infancy. I relied on the free newspaper the Mirror to get the right contacts and basically learning by doing.
I had called an SP advertising for an incall. She said she was available and was at XYZ hotel. So I drove to the hotel and went to the hotel counter and asked the concierge if he had any girls available. The concierge proceeded to open up the yellow pages and told me to call 123 number. So I left the hotel puzzled that I did not get to do the incall. It was only later on that I realized that I was suppose to call the SP back to get the room number!!! The conciege must have been wondering what this guy was smoking....
That was my newbie mistake, I'm sure alot of the older hobbiest have some stories when starting out since there was no internet to get information on how the hobby wolrd worked back then.
