I would rather someone file bogus expense reports for a vacation in Belize than overcomplicate my work to justify their own importance and in the practice stop me from advancing and getting a raise to go on my own vacation in Belize. The later case is super common, 100% legal and 100% greater asshole because I am deprived not only of some of my money but also my time and dignity. Everything comes in degrees and I would rather deal with someone who is a little crooked but still well meaning towards me than someone completely honest and a complete jerk.
