This list will be a constant work in progress because people saying stupid things will never end.....
  1. Do you have this in any other colours?
    Reply sarcastically "yes, they're not on display because we don't want to sell them to you"
  2. I'm 60 and I think my feet are still growing. Can you measure them?
  3. My fingers are feeling really tight in these shoes
    Maybe you should take your hand out of the shoe then
  4. I think I'm either a size 6, 7, 8 or 9
    Well, which one?
