I'll be visiting CR in the near future. I typically use SA for my dates, and was just curious of any scams I should look for, assuming they may use different tactics than in USA.
I don't know what SA is but I suggest just meeting a girl at the hooker bars. That way you can get a vibe from her before pulling the trigger.
CR is YMMV, so you're definitely better off meeting them at a bar and discussing up-front what you're looking for. Otherwise, you could end up with a provider that doesn't offer what you're looking for.
