Telling the whole long-winded story for info.
My mum is a keen gardener but is elderly now and widowed and has been gradually finding the heavy work around the garden more and more difficult.
Last summer she responded to a flyer posted by a couple who live in the same village advertising their gardening and odd job services. The arrangement was that they would cut the grass for a set fee each week (£10 a cut) through the summer months and if and when anything else needed doing they would charge an additional fee. Cash in hand. I've never met the couple, all i know about them is through my mum.
So; Mum relays all her conversations to me in great detail and after a few weeks i was hearing all about this couple and how they live in a 2nd floor flat and yet have 2 ride on lawn mowers and big power tools to store. Soon they were telling mum how they had been told to get their stuff out of a nearby barn they were using as the farmer wanted it back for his livestock. Lastly they told her they had ''no idea where they were going to put it all''. Coincidentally this last bit was just after mum had walked them through her large, mostly empty, double garage for some thing or other.
Mum told me she offered to house the largest ride on lawn mower in the garage and they had bought it round that night. I asked how that was going to work out if they needed the machine while she was out and she said it's fine she'd given them a key! I was a bit 
- but she was adamant she wanted to do this for them. I asked if she was going to charge any storage fee and she said no, but she had suggested they do her gardening for free in payment for the permanent use of the garage and they'd said yes.
2 weeks later and ALL their stuff was in the garage, taking up the whole floor area. DH and i felt that mum was being a soft touch, and that she'd been a bit quick to give virtual strangers a key to part of her property and permission to come and go as they please. (They now do her gardening when they are picking stuff up out of the garage or dropping stuff off, not by 'appointment' as it were). It's hard to say much to mum about it as a) she is quite feisty and doesn't like to be challenged, b) she is clearly enjoying the extra 'drama' in her life of having these people coming and going, (waving at them out the window etc) plus c) she feels she is being helpful.
The fact that mum was getting her gardening done for nothing made me just been bite my lip bout the garage when she tells me how wonderful and kind they are.
So - to get to the point - today i find out from one of my DDs who were round there last week that she is still paying the couple for their gardening! DD saw her give them money.
I haven't raised this with her yet but i know what she'll say. It'll be oh how nice they are and how good they are at cutting her lawn and how they need her garage etc.
This is taking the piss surely? They are meant to be running a proper business but are using an old lady's garage as storage for their equipment and more than that it seems are still charging her for her gardening!
DH suggests getting hold of their number and 'having a word'. Mum would hate it if she found out.
What do you think? WWYD?
