Signs it's NOT legit only:
- If the place looks a bit grotty or dubious. Late opening hours, LED sign in the window.
- Low door fee, say £50 for a hour. Suggests the real money is made from "tips"
- Walk-ins, no appointment needed
- No discussion of your reason for being there, injuries, rehab, skin conditions, the type of oil you want... just "you get on table, I come back"
Ultimately though you just have to bite the bullet, if it's an unreviewed place. If extras are on offer the girl is usually forthcoming, you won't have to convince her.
