Pesky paranoid client!

I see his point. I really do. I'm more than aware that Other Leafleteers are sometimes less honest than me and actually do chuck all their leaflets over the nearest wall and trot back to the office with their paws out. But I have spent the whole day fretting about how come the new client reckons he did a random check and found no leaflets delivered. I know I was in the right road. I know it was a straight road with clearly marked houses, unlike some patches which can be a demented nightmare of back alleys and unmarked offshoots and all sorts. So I have been asking myself:
How many dogs were there on that road that could have eaten the leaflets?
Could the bizarre freak windstorms in fact have sucked leaflets back out of letterboxes and dissipated them?
Are householders with longstanding objections to leaflets (but not such big objections that they actually sticker their letterboxes) deliberately claiming they didn't get leafleted so I do not get paid and then the bailiffs get me?

I have been known to declare, straight-faced, that workplace problems must have been down to 'poltergeists' but not sure that would wash this time. Still, perhaps the client will get some clients and cheer up. And pay us.
