I had a job once, got there and the heavens opened (it was forecast only to be overcast, they got that wrong!) and would not stop so could not get on, went back 2 days later, got setup and my pump decided it did not want to work, gave up and went home. Ordered the tool to fix the pump, went back a week later, 3rd time lucky and did the job. Lucky the job was only 5 miles away.
It felt as if some force was trying to trip me up every step of the way. The customer saw the funny side and was ok about the whole thing.
