To ask if you would report a friend…

[Catsfredwilma]

….who regularly drives whilst under the influence of drink and drugs.
Not asking for all the reasons why reporting is the right thing to do. (Crime stoppers, anonymously).
Asking genuinely, would you honestly actually do it??
YABU….no, I couldn’t do it. I couldn’t get my friend in trouble.
YANBU….yes, absolutely, I would report.

I would absolutely report and ditch the selfish wanker friend.
Sorry, but they are actually putting lives in danger.

I have previously done so, and I would again 100%.

Depends. If they were clearly drunk and incapable and refused to stop then yes
If occasionally had 1 or 2 but totally competent then no
