Famous quotes containing the word stern:
“We tried pathetic appeals to the wandering waiters, who told us “they are coming, Sir” in a soothing tone—and we tried stern remonstrance, & they then said “they are coming, Sir” in a more injured tone; & after all such appeals they retired into their dens, and hid themselves behind sideboards and dish-covers, still the chops came not. We agreed that of all virtues a waiter can display, that of a retiring disposition is quite the least desirable.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
