While you could try hitting on them at work many will be to shy to want to exchange numbers with foreign men right there in front of their coworkers.
Instead the best way to contact the many Filipinas living in Abu Dhabi seeking foreign men is by using the dating sites.
They also will be sending a lot of their money back home to support those families and won’t have much disposable income.
This means that if foreign men will be friendly and treat them to a nice dinner or drinks in the nightlife they will almost assuredly accept that offer.
Instead you can go try to get free sex from Abu Dhabi girls who want to hook up at places like Empire Yas, Hookah Lounge, or Barfly.
