I was there a few weeks ago,, i think there was water...
I happened not to carry cash with me and instead put the kenyan currency in my luggage awaiting my return. I only had a few coins in my carry bag, totalling to 50/-.
Unfortunately, I couldnt get any water for less than Ksh. 100 at the duty free shop. Why do they call them duty free ?
I ended up drinking water from the taps in the washrooms.
