I read the FAQ for booking HGs.
How do I book a HG?
Look for your choice of girl in the 141 DB. Call the number provided. Some of the agents speak English but most don't. So keep the exchange simple. I mean absolutely no chit chat no questions.
You: Girl xxx today 5:30pm ok?
Agent: ok. Hotel xyz. Call me at the lobby.
That said, a lot of the ads don't have any names.
Example: lv, yy, nn
Some of the same letters are used for many girls. I count 9 lv girls in PE alone at the moment.
How do you specify which girl you want without anything that sounds like a name in that simple conversation?
