This story is what I imagine it must have been like arranging a massage before we had access to the WWW and mobile phones etc so set it in the 1980s.
Ads in local papers etc where the only place you would have been able to find classifieds for "massage services" these where using at the back of a tabloid newspaper You would have to phone them and they would give a general area in the city where they were based so a bit hit and miss before you found somewhere close by. The character in this story wanted to have his first massage so this is what I think he would have done.
HeI bought a copies of various newspapers one Friday headed home and started the phone around, always quite a nervous experience as your phone number would also be available for them to see. After a few fruitless calls he found one about 10km away and the lady who answered the phone had a nice voice, not the most scientific method for choosing but better than nothing. They arranged an appointment for 10am Saturday and she gave him the name of the road where they were based and told him to call when he was in the area with specific directions to follow then.
Saturday morning he was very nervous thinking of all the things that could go wrong, would it be run by a criminal gang, maybe the police would raid the place etc. Anyway he put those fears aside and drove to the road she mentioned. He parked about 10:45 and started looking for a working public telephone which he eventually found. He called the number the same lady answered she seemed a bit confused re 11am appointment which didn't fill him with confidence, see gave him directions saying their door was between a newsagent and shoe shop go up 4 steps and he would see a white door.
He walked in the direction she gave him, heI thought everyone knew what he was heading to do complete paranoia. He saw the shoe shop and quickly glanced to his left checking for the white door but kept walking. He walked another 20m then did a U-turn took a deep breath and walked up to the door then ringing their bell. Seemed like an age before it opened when it did he couldn't see anyone but a voice from behind the door said to come in quickly. He entered and heard the door closing behind him, when he looked around a really attractive women was smiling at him, she was late 20s early 30s about 5 foot 4 with great slim figure she was wearing a uniform dress you would typically see in a spa so very professional looking.
She introduced herself as Linda and invited him to follow her up the stairs she showed him into what must have been a bedroom at one time in this Victorian house, huge room with high ceiling which contained one chair and weirdly an empty jacuzzi. She said that the lady who does massage is currently busy and would he mind waiting, He was committed now so felt he couldn't back out so confirmed he was happy to wait. She closed then locked the door now his paranoia hit a new level, what if she left him there, what if the house went on fire how would he get out.
