Tips on Group Meals are to be reasonable which Penn State generally considers to be 20% or less. However, tips that are $1.00 or less over 20% are acceptable and should not be deducted.  

If there is a tip overage greater than $1.00 on a group meal, the amount of the overage should be itemized out of the Group Meal PCARD expense and marked “Deduct from Reimbursement.” Do not use a "Reimbursement Reduction" to reduce a PCARD transaction.
