Thankfully the State Dept takes care of the lease, water and electricity or we would end up waiting in line with a bag of cash to pay the bills (or you can pay someone to wait in line for you).
Regarding the prostitutes, you will often see young women dressed to the nines in any bar where expat men congregate, especially French military and businessmen. These women are not prostitutes, but they are definitely looking for a sugar daddy. Here in Libreville, a sugar daddy refers to someone who is definitely white, usually bald and fat, often unattractive and can afford to eat out at a restaurant...any restaurant. We often notice young beautiful local women with an unattractive white man on one arm and a baby on the other.
After 10PM, you will often see women gathering on street corners in close proximity to one of the hotels. These women are more interested in a direct cash transaction rather than a relationship. The oldest profession.
