To be reimbursed for breakfast, you must leave by 7:00 A.M. lunch by 11:00 A.M. and have dinner by 5:00 P.M. To receive reimbursement for breakfast, you must return later than 10:00 A.M, lunch later than 2:00 P.M. and have dinner by 7:00 P.M. On a trip lasting more than one day, we allow hotel, taxi and airfare, as well as meal allowances. The same time apply for meal expenses.” Draw a decision table and Decision table for Clyde’s narrative of the reimbursement policies
