I agree with the safety processes from Samantha and others on this. I would like to add that seeing a client more than once in the same space whether in call or out, does fall under the law as a common bawdy house a.k.a. brothel...However, since the recent appeal, there has been less movement on the part of law enforcement to move forward with raids, sweeps and the like, especially for individuals vs. incall agencies
One of the pro's that accompany working from your own space - wherever that may be- home or a rented space- is that many clients upon visiting you, do tend to act as guests on your turf, and as such are likely to display certain levels of etiquette that reinforce your position as host.
