In a billingual province such as Quebec, you have to greet people in English and in French when you work in customer service. After a while, it just becomes one word because you're so used to repeating it over and over. As well, it MUST be "bonjour" that is said first, because French (on the whole) are unforgivably uppity. And don't even THINK about just saying "hi!"
For those new in customer service;
"Bonjour, hi! Est-ce que je peut vous aidez? Can I help you?"
And after years of apathy in customer service;
"Bonjourhi. Est-ce que je peut vous aidez can I help you." (Said all in one breath)
