I in california have all kinds of "service fees" too. Despite them successfully campaigning to make sure delivery drivers here do not count as employees.
Don't fall for the spin. This is just an added cost they always wanted to add. If Mamdami wasn't in NYC, they would just call it a "service Fee" or "delivery fee" (which is different from the Driver's Tip) like they do here. Or make up a anew fee altogether.
