What is this world.coming to

I’d look at the set-up. If it’s a young geezer in the road with others standing nearby, then I would be wary of it being a scam.

If it’s an older guy, all by himself with a bona fide vehicle, rather than some fairground tug - then I would almost certainly stop.

id most likely do the same depending on location.
standard practice nowadays is for your junkie slapper to be hitching a lift with here equally junkie boyfriend hiding 100 yards down the road.
if your stupid enough to stop for her,then your nicely placed for the 2 of them to be clambouring in with the needles dripping in aids ect.
if i did stop,it would be with the cab locked,and my eyes wide open.
