Only once have I had a WG visit me at home. Almost all I met were:
1. At their homes, which in the past 10 years is the majority of times
2. At a brothel. These brothels were mainly massage parlours (although I haven't visited one for about 15 years) or flats (either two or more WGs available on the day or a single WG available each day)
3. At a hotel which the WG had booked for the day, have done this twice recently
4. At their flat which they leased, but I've only known two WGs to do this
5. Bar fining a girl and taking her to my place, but only in Asia (Bangkok, Hong Kong, Singapore, Manila)
