The touts have been surprisingly low key. They stand and urge but on the whole, they do not follow, block your way or push against your personal space.
Not surprisingly, but more than I expected, French is the dominant language spoken to western-looking people. It seems (especially based on my travel-day) most men at least are entirely fluent in French, the language of their most recent colonizer, and Arabic. Spanish comes next, and then English. (I had so many conversations in Spanish – far more than in Spain where more people speak English.)
Merchants of course can get by in English and Spanish too, because they want your money.
