Whatever it is called with that kind of caffeine content you warning label it with listing of exactly how much caffeine it has. Well maybe unless it is named literally "coffee" and is plain brewed coffee and at that brewed coffee with the normal levels of caffeine coffee contains.
Ones frappe, whippazino also better have needed labels in cases, since given all they mix how the heck one is to know what exactly is the contents. Oh this is extra special "angry frappe" with double squared shot expresso, so exactly how much caffeine is that dear seller per one glass? I just thought you put chili in it or something to make it "angry", but has literally multiple times more caffeine content.
This is why all the energy drinks atleast where I live have the ever present "contains high amount of caffeine x mg/100ml".
You sell something like that as counter served item with no packaging label to read, well now your menu list must contains at minimum highlights. Something like "our special drunk (HC)" and then somewhere on the menu there reads "HC means high in caffeine". Then obviously at the counter must be a full labeling booklet of "here is our every product from the plainest brewed coffee to our jumbo mega sandwich and special brew beverage with full nutritional information and ingredients"
Just like one can't sell say a pastry in cafe with nut creme filling with out having a big marker on all the menus "contains nuts, nut allergies bevare". Since similarly nut allergic consuming nuts can be life threatening, well for some people consuming caffeine isn't healthy and must be disclosed.
Then again not like the "very shoot ourselves in the foot, but just little bit, instead of lot" on decades long repeat leads to anything good.
If ones vote is to be taken for granted, you have no power. Only way you can hold your own side accountable is by threatening to withhold the vote.
That is bargaining. Voting Democrat nomatter what and after that asking could they please do something, that is begging. Begging rarely works as well as bargaining.
Damned if you do, damned if you don't. Joys of two party system.
Most likely people just get apathy and instead of flipping to Trump, they simply stay home. Which is the other bargain. What you offer for me to bother to go from my home to the voting station in the first place.
That is their play "you can't take us for granted anymore, we care about our vote and bargaining power on long term enough to suffer on short term to buy long term relevance".
Whether it works is different matter. I don't know, if democratic leadership has the where with all to take their left flank of voters as anything but given serval supporters to be kept in line with "but we are only little bit bad, those guys are really really bad".
