I'm at a liscensed store and annoyingly we don't have cold case(it's while thing that pisses me off because we're one of the busiest stores in our division but if the add a cold case they'll also have to expand our kiosk and add stuff like nitro and they don't want to spend the money just yet. Sorry for the rant, just uuggghhhh).

But at my last shift (alone) I had a kid come up and ask for chocolate milk and figured I could just make some. The kid seemed happy with it anyway. I just rang up milk with mocha and threw it in the shaker, is there any other specific way to do this or this the best option
