i think the problem lies here:
"some nob stole my aerial, what a bunch of cocks!"
"here mate, have mine"
"wow, thanks!"
or
"can i have a free aerial please"
"mm no a free one but i can give you this one for insanely cheap?"
"mm no thanks, i'll hold out untill someone gives me 15 quid for free."
just comes across all wrong if you get my meaning?
