Yep, it’s per song.. what I do sometimes is ask them to count off the songs while we’re in the back and/or say I’d like to go back for at least 3 songs (or however many) but please let me know when we’ve reached that number, and then I can ask them to stay longer with me if I want, but at least I’m not surprised.. Usually they’ve been ok with it. Probably helps that I ask in French/Franglais, smile and say please :-)
I’ve found that most Montréal dancers have been friendlier when I speak French with them or at least try to. Occasionally one will want to practice his English but will let me speak a French to him..and there is nothing sexier than a dancer purring (masculinely) “J’adore” into my ear (I won’t say in public what I may have been doing to prompt that reaction ?)
