I meant this sort of thing:
You stick it on top of the cup, stick a filter in with coffe and pour boiling water in.
I've been experimenting with a few homemade ideas but they're a bit fiddly. However, it seems like getting hold of one of these is really quite hard.
Robert Dayus (sp?) don't do them; yesterday in John Lewis a rather Eeyore-like old member of staff said "We don't do them...Debenhams don't do them...Selfridges don't do them...House of Fraser don't do them...there was a shop in Hampstead that did them but it closed down 6 months ago...".
Seriously, anyone know where I can buy the fuckers? At this rate I guess I'll have to get a cheap bit of plastic flown in from the States.
