Six shakes, one price, built around what you just did to yourself. Pick by training goal, not by flavour. Coffee too, because the 06:30 class exists.
If you're the kind of person who refuels after every class, you should be the kind of person who gets one free. Ask for a loyalty card at the bar; we stamp it every shake.
Ask for one

The bar is the one part of jeem that isn't hard. Shakes, coffee, water, and the post-class debrief where everyone agrees it was the worst one yet.
