With our squaddies custies, you don't need a 1 liner really. They know eachother and are very compact. So if I drop and replace 1, all the neighbours notice pretty quickly lol. On the second time around, we tend to get the "Oh, you don't clean nr..... anymore" type of comments.
and the gossip starts

Another time, some bird was going on holliday, saw us working and legged it over all breathless to pay us. I said "You're keen", she said "Yes, but we are away back to UK in a couple of hours, so I wanted to pay you before we go, so we wont be taken off your list".
Had another woman ring us from South Wales once. We cleaned her and didn't manage to catch her before they moved back to UK. She remembered to pay but couldn't find our number. When they got the furniture unloaded, she found our card stuck to her fridge door. Rang us to say sorry and to collect from her mate in the same street. aaaaw sweet

Had a few do a runner though. Not many, but annoying all the same. The 3 strikes rule that some of you have is a good idea.
