I ordered a packages on Thursday, thinking it would arrive by next Monday.
I ordered a book I needed for my class. Monday has come and passed, and I don't have the book yet.
Now I'm going to be docked points for turning in not being able to turn in an assignment (because my professor doesn't accept late work)and it's all because of UPS' incompetence.
If someone pays for two day shipping, you might want to ship it in two days.
But hey, I guess I should take comfort that it's only a few days late, as opposed to not receiving the package entirely and having to waste money by stopping by a delivery center to pick it up.
