I've never had any of the PITAs described here, but then, I've not done many audaxes.
On my first (Dorset Coast, about 1992), I was caught by a group who'd left the first control behind me, & asked me if I was riding alone. When I said I was, & it was my first, they tucked me into their group & towed me to the next control. Nice. They then rode on & left me, but that was fair enough. Towing me all the way round would have slowed them down an awful lot.
