That sort of thing makes me so ! Why does it seem people (in general) are so damn ignorant? For example I went into my local (VERY rubbish) reptile shop yesterday and the dialogue went as follows (for reference i was trying to decide wether or not to move chloe up a prey size).

Me - 'Hi, can i see the size of your weaner rats please?'
Owner - 'What are you trying to feed, how long is it?'
Me - 'Erm a royal python, she is about 2.5ft and about this around (gestures with hands)'
Owner - 'It doesn't matter how fat they are, its how long they are which decides what they can eat'
Me - 'Some very experienced royal python breeders tell me its there girth thats important'
Owner - 'There wrong, here she should be able to eat this medium size mouse'

I decided not to challenge her as she has several bp's in the same cages, all with no hides and with stuck shed.... so enough said.
