I do a lot unpaid, to help, to assist, time is given to others in many ways.
I always have done it, that’s my style. I’m like that and sometimes, when somebody asks me "what can I do for you?"
To keep it simple I often say, with a smile: “just buy me a coffee"
Every now and again I am surprised with an extra one.
One or more, whenever it happens it is a lovely surprise.
Have a good day / week,
