Since I don't live locally in HK, I get a prepaid sim when I get there... so no tracking in regards to communication...
ALWAYS have plenty of cash....
Fake name, of course...
Extra condom discretely in a pocket (just in case)
And even if the girl is realllly cute, and even if we really had a blast (pun intended), I NEVER give out any real personal info...
so if they bump into you in other places, and the WG starts a scene, you can call her crazy when all her info about you is false.
I'm from a different country, with/without kids, married/girlfriend/single, my occupation.
Come up with a believable story, that's memorable and SPECIFIC... so when it's "wrong", you have plausible deniablilty...
Yes... I'm that paranoid...
Take note, that in general, I try NOT to keep a regular (even here in the Philippines)... just too much risk in getting exposed.... not worth taking the chance....
YMMV though...
