French can be a deceptively familiar language because of the number of words and structures it shares with English. Despite this, it's far from easy, though the bare essentials are not difficult to master and can make all the difference.
Even just saying "Bonjour Madame/Monsieur" and then gesticulating will usually get you a smile and helpful service.
People working in tourist offices, hotels and so on, almost always speak English and tend to use it when you're struggling to speak French - be grateful, not insulted.
