Although I've only been going about 3 months, starting to hear them. Some are because I'm new to the customer, and not built up enough trust yet - " you've missed bits " - when the marks turn out to be inside and they couldn't see them before because they've needed cleaning for a while..
Best was last week " You'll have to do them when I'm in so you can get to the back, but I'm in and out all the time so once a month I'll ring you when I'm in for a bit and you can come round then and do them " :

Yesterday -
" I suppose you'll be packing up for winter and finding something else to do "

Yep, sure lol. I'll just "find something else to do "
