You get a sense that whole airport is corrupt and asking for a manager wouldn't help. You could play their bluff, but when they have valuable items of yours that's not really an option. So you feel helpless and succumb to their demands. Even tho tip was not much, I can't tell you the horrible feeling it leaves you with & that now you are contributing to the problem! I am hoping to get the word out and that an expert TA may tell me who to report this to...US Embassy? It's so sad because the guides were telling us how Zanzibar is really hoping to place its self on the tourist map. This is 1 place we will not be back to. I'm sure the future will hold demands for specific amts of money instead of just "TIPS"! Please BE AWARE.
