Duck feet means always having to try before you buy. And even then you sometimes get it wrong. I had to return my daughter's sandals to the shop because she bled onto them, even though I (with a lifetime's experience of duck feet) and two trained shoe fitters thought they fit.

(To h-l: charge at least 50% for the missed lesson, even if they don't pay you. At the very least they owed you a perfunctory "sorry" and I bet Miss Manners would agree.)
