I do like WDW, but bwa ha ha ha ha.....
Oh they are so small. I get what JK was doing/asking for, but she just wasn't thinking. Just like her "no soda" thing, when the ingredients in butterbeer aren't HEALTH food or anything (when I first went, the TMs had the ingredients on a laminated sheet under something on their stands, and the TM I asked showed it to me...I scanned it to make sure none of DS's sensitivities were on there, but man do I wish I'd taken a picture instead!). Or looking at the ingredients in most of the candies in the candy shop, it's the same ingredients as are in soda! Silly silly.
Someone should have used commonsense. It's lovely that she believes in a world of slim people, but that's not even totally true in England, let alone in America. If Hagrid (the character) tried to go into those shops he wouldn't be able to get through the door.
Plus, in the *magical* world, it would look small from the outside, but expand! So it would be bigger on the inside than what you thought...
Anyway, yes, I hope for shops that allow for normal people to move around without smooshing up against strangers.
