We recently started requiring a deposit for large parties at our wine bar. i made a button to ring in a ticket for half the normal amount to reflect the deposit already paid. my bar tender brought to my attention that this leaves them with only 10% gratuity rather than the 20% we would normally put on a ticket like this. i want to make sure my employees are getting their full tips and not getting short changed. is there anyway we can add a manual input gratity or import the deposit from stripe some how
