I know maybe it is a bit controversial …
Test for friction…
It is not healthy looking for red flags ..
When there is a stressful situation…
Let's say , your card is declined ..
Or you left your wallet behind…you are in a restaurant ..
The person says , that's alright , I can sort this out..
Or your car breaks down..no problem , we can figure this out..
Work it out together ..
If under a stressful situation, the other person is calm and relaxed..
