I went to do a IT job in Newlands about a month ago. Was a quick job, basically powered off the TV box and powered it on and it worked again - then I just checked everything was seated nicely and quick 1 hour charge.
I stated clearly in the Whatsapp my rate for the hour.
2 hours later I get the amount but with an added 0 but I didn't take notice as I was busy.
Life carries on, a week later I notice my account has a bit more money in it than it should so I check my account and notice the lady paid too much - I sent her a Whatsapp asking her for a banking details so I can refund her - nope, she was not interested in giving me her banking details, "you were amazing and I will continue to use you going forward and don't worry, I won't make the mistake again but you deserve it - thanks for being honest"
The money is still sitting in my account "just incase" she asks for it back.
Some people have more money than they need.
