How can people be so lazy?

Not a good day working at the campground office.  We worked with a fairly new couple, they did NOT want to do ANYTHING.  She just sat and read and filed her nails.  He disappeared when there was anything to do.  They were sure to take a break and go home for dinner for 45 minutes.  (We do neither, when we are there to work - we work.)  I finally got busy with another project and she had to get up and work.  At one point Don got really mad, which is rare for him, when the man flat out refused to help Don.  We have talked to our boss and found out we aren't the only ones having problems with them.  We also said we never want to be on the schedule with them again.  - Larry and Jane - be gone~~~
