أي لغة تتكلمون؟

I want to ask Arabs. Please tell me guys how often do you have to speak Fusha Arabic in your everyday conversations.. I want to learn Arabic, I'm going to Egypt soon on holiday, and I need to know for what I should be prepaired.. Say, can I come to the store and speak the Fusha Arabic, I wonder if I would be stared by everyone as an idiot then? Please tell me what would you think and feel if someone one day greeted you in the street and started to talk in Standart Arabic to you? In which language would you reply? And if one asked you to talk in  Standart Arabic instead of 3ammeeya  would you do that and how easy would it be for you to talk in Standart Arabic in your everyday life? 

I tell you why I warry - in Russian forums there's an opinion which is very popular - the Fusha Arabic is almost useless for street conversations in the store, in the beach, in the museums and at the bus stations.. There's even a Russian joke told by one tourist or someone.. When the Russian took a taxi and told to the driver where he need to go (in Fusha) the driver answered "صدق الله العظيم" thinking that the Russian was reading the Quran..  This is a funny story, I don't think that it's true and the Arabs do understand Fusha (I see that many cartoons for children in Standart Arabic and hosts of many programms speak it).. But anyway I am afraid that the Arab I will be talking to replys in his native accent and I wouldn't understand him...
