Reimbursement for a tip of up to 15% of the charge is allowable when hosting groups or guests. The 15% limit does not apply when the establishment adds a service charge for larger groups in lieu of gratuity. In this case, the amount of the service charge is not within the control of the customer and the full gratuity (e.g., 18%) can be reimbursed.
Tips or fees for alcoholic beverage service are not reimbursable from E&G funds. These costs need to be separated and included with the alcoholic beverage purchase. (See the "Getting Reimbursed for Alcoholic Beverages" FAQ for more information.)
