asked for more than they actually need, because they are so worried that they won't get what they want in the first place?
this happened to me actually
i wanted to get 3 songs by the beatles.. just 3
how ever, i ended up totally flipping over it, and asking for all the albums, even though inside i knew i only wanted the 3 songs.
couldn't do it- for some reason, i was so worried i wouldn't get them i had to ask for the whole collection.
but luckily i got them now- the person organising the whole collection for me must have been totally anoyed
