Built a drawer like that once. Called it "wrong".

We spent the weekend at the St. George (Utah) Parade of Homes--half a dozen
million dollar homes (out of 25).

I noticed in a couple of them that the drawer slides were not the usual
"self-closers". They actually were hard to pull out for the first few inches
and when closing the last few inches would fight to close. At first I thought,
electric drawer closers? Then I decided they must have strong magnets. What's
the real story of these drawers with an attitude?
