Stop with your false information.you got 2 types in Dubai. the white ones who hang around in the hotel nightclubs/pubs and will cost an arm and a leg ..or the cheaper Centra Asian and Filipino ones in Deira. walk on the street near Traders and they'll lock eyes as you walk.
Qatar is similar. the nightclub at Sheraton resort is a meat market. mostly Chinese. the TGIF at double tree in old town has Filipinos in Thursday Eve.
Africa is generally horrible. I've had good luck in hotels in Nairobi, but be very very careful going to brothels. also the road opposite Hilton has street action.
Qatar, really !!! , yeah go for it & watch yourself getting beheaded.
