I tried to get some coffee at a conference the other day.
…placed cup on saucer…put cup under spout of preprepared jug of coffee-like liquid (Yeuk, is I believe the correct spelling)…not paying attention due to being talked at by several delegates…press dispense handle…cup not under spout…coffee mostly on saucer and table.
Well, conference organisers could simply put the saucers at the far end of the table so that only full cups land on them (or do away with them altogether -or even provide fresh coffee).
Failing this, today’s invention is a simple clip-on device which invites a saucer user to push their cup to one side before filling from one of these machines.
