Venting about travelers (semi pun)

I've been traveling for awhile now. From what I've seen, half of the travelers that I've encountered shouldn't be traveling, i.e. inexperienced, lazy, liars (falsifying experiences), narcotics using, etc. I suppose there are staff members that could and do do these things too, but we all know travelers have to set themselves apart from the staff by providing a higher standard of care. Are there things that could be done to rectify this? I could list several things, but it probably wouldn't matter, since nurses, new and old, are too preoccupied w/ the notion of traveling and not doing what they're supposed to do when they're actually there at the hospital/facility. Please do us travelers a favor and travel only when you truly want to make a difference; since I’m already trying to adjust to a new environment and not having to worry about other “travelers” screwing it up for everyone and me.
