Is adding a second day to travel (without actually traveling on it) to obtain an accommodation and transportation allowance sufficient to cover high travel expenses considered bearing false witness, given the inadequacy of the official allowance and its causing personal wages to be consumed?

If the law stipulates transportation and accommodation expenses to cover costs within what is customary, but the specified amount is insufficient, leading to a deprivation of the employee's right, then it is permissible to follow the common practice in government sectors by adding a second day to cover expenses, provided that authorized officials permit it.
