one of my worst was i was doing a one off insides for a german couple , big old house . it was about 9 a.m. and as i wiped around the frames id built up a big blob of cobwebs on the tip of my rag. well i flicked the rag and the blob let go and dropped- right into a large jug of fresh orange juice on the kitchen table. what could i do? not a minute later the man of the house comes and carries the jug away into the breakfast room , bet it tasted lovely!
