it was a busy st I did not want people to watch me on my phone on adultworks
NOBODY is watching you on Adultwork on the street unless you do something daft like stand in the middle of a road or busy doorway!
Even better, do your research at home and have several tabs open to your options ready to call.
If you don't want to save bookmarks then use something like Pocket or Pushbullet to "save" your choices.
Also, if you're in the Whitechapel area then it's a short stroll over to Middlesex St for the 4+ parlours for you to chance it in.
