Even in private industry this happens. I have referred people to companies only to have them tell me they were used for walking dogs, picking up laundry...
It's embarrassing and unprofessional.
Well, there will always be jerks. If I'm not happy where I'm working, I don't stay. Occasionally my bosses have "asked" me to run errands. Easy money , and I didn't mind helping out. I have watched kids in my office before while their parent is busy. It's only degrading and unprofessional if it bothers you. If it does, move on.
Private industry is owner or investor money. Federal government money is my money, and yours.
Please do not compare private companies to government.There is a world of difference. Government takes, business gives. Government is a parasite and lives because of private business. To mention the two in the same breath is to demean private companies.
