Orders please

Having trouble remembering what all your colleagues want to drink? Or your
friends in the bar?
Simply tap the name of the drink and the number increases. Add new drinks or
delete unused drinks.
Made a mistake? Press the drink until the menu appears and hit 'Decrease'. It's as simple as that!
And when the order is complete hit Lock, that way you can't accidentally increase
any amount on the way to the bar or coffee machine.
