Meals that only include Cornell participants in travel status are not considered hosted meals. For all meals while in travel status, each Cornell traveler will be reimbursed at per diem for each meal not otherwise provided by the conference or meeting. Therefore, each diner should request a separate check or split the check. Most restaurants are able and willing to do this without issue.
A hosted meal includes a non-Cornell representative and will be reimbursed as a hosted meal. Generally, the senior-most member should pay for the hosted meal and seek reimbursement.
