Diner Level 23 Objective 2

I've achieved every objective on every level to this point, but I cannot get this one. This is the one where you have to serve 12 drinks - I never get anywhere near 12 people ordering drinks.

Has anyone achieved this objective?

ahh never mind, it suddenly jumped from giving me 6 or 7 drinks orders to giving me 15. Another one where you have to just keep playing til the planets align/

Did you have trouble with Objective 3. I have no idea what item they want me to keep.

Give people coffee even if they don't ask for it. I usually order enough coffee to meet the objective in the beginning before making food since there is a little money to start, then I focus on giving them coffee over and over, same people at counter, until the green checkmark pops up. good luck! PS Do a trick or two to keep them happy, still enough time to make money after.
