At the moment, it appears as though custom modifiers that staff add to an item in a fine dining restaurant are automatically shown on a customer bill when printing the customer bill. There appears to be a setting to hide them on customer receipt. However, 95% of most fine dining establishments provide their customers with a paper copy of their bill. It's very embarassing for some customers who are part of a group and if the company / CEO is paying the bill, they can see the custom modifiers that are non-priced (i.e. No dairy, lactose intolerant, etc.) for an employee or individual that is dining as part of the group when the bill is paid in total.
