yes me, about a week ago.
i told him to put them as spar up his backside he could get them

not really.
just told him they don't work
"oh yes they do" he said
"oh no they don't" i said
"oh yes...... you get the picture
"okay i'll pay you double at the end of the year providing they work for me"
"we don't work like that"
well in that case, "oooooooh no they don't" i said

so to sum up.....
yes spar called me and i turned them down politely
