Sheeeesh,
I have helped a retired couple for a few years now, I haven't under cut myself, felt a bit guilty for charging them a few times, considering it was for something minor
I have learnt a lot from them, and enjoyed their friendship.
I finished a few jobs for them, a few Grab rails about the house/showers, toilets, from and rear steps, overhead cupboards, replace a dishwasher, modify a cabnet for a new oven.
Erect a 6x6 Carport.
We have never discussed payment, they have always to leave an envelope in my vehicle without me knowing.
Got home this arvo, went to recharge the batteries(18V Makita gear), and bugger me there is an envelope.
That will help out heaps, they have found time to print off a copy of what they have deposited to my account.
So very thankful, hmmm
I am humbled.
