Because it usually looks like this:
We were fortunate to have a hotel room cater-corner from Voodoo Doughnut, the popular doughnut shop in Portland. The lineup is at least as long as in the second photo from just before 9 a.m. to well past 1 a.m.
Note please the entrance to the shop is on the corner. The line forms in two directions to it.
The shop is open 24 hours each day except some holidays such as Thanksgiving.
The first pic is at 6:34 a.m.
The second at 2:48 p.m.
I will post about our doughnut escapade in the near future.
