Would you have walked on by?

[FatLazyContractor]

I'd have probably tentatively tried an "are you OK?" and happily accepted a "yes" answer. Difficult to know what to do.

And if he replied, "No, I need a shag" ?

I've saved someone from drowning, as expected they're embarrassed and not altogether happy about being saved

In hindsight, I was lucky I wasn't sued for some spurious reason

Embarrassed - understood. Not happy - that is not expected.

Remember NF's Monday links about survivors who jumped from golden gate bridge?

Some guy jumped then thought "All my life problems are solvable. Apart from having just jumped from golden gate bridge".

If you see him again, tell him that his ID Suityou01 was locked due to inactivity.

naughty!

And if he replied, "No, I need a shag" ?

I'm sure she could have passed on your details.

Just had it confirmed he was taken to hospital by the ambulance service

Well that's a week's food, clothing and stay sorted then!

Will you declare yourself as witness/possibly the last person he saw?

[GlenW]

Will you declare yourself as witness/possibly the last person he saw before he died an agonising death?

FTFY

[MarillionFan]

Will you declare yourself as witness/possibly the last person he saw?

So he can tell the police about how he walked away and then immediately posted about it on social media?

[mudskipper]

Last distressed person I mumbled "You OK?" at didn't give the anticipated "yes" response. So I ended up being agony aunt to a weeping woman for over an hour on the train home. Edit: She didn't ask for a shag though.
