Modifiers: These are, like they sound, used to ‘modify’ the order of an item.
They may not always have a price and if they do it is usually a small amount.
The best examples of a modifier is ‘Skim Milk’ or 'Weak' for the Item of a Cappuccino.
Other examples might be 'Rare' for a steak or a flavour of mixer for a spirit based drink.
Modifiers cannot be ordered on their own. They must be attached to an item.
You can attach as many Modifiers to an Item as you wish.
Because Modifiers are attached to Items, they will print at the printer governed by the Items settings. You can find out more about this here.
Modifiers always appear in Front Office as Italicised.
