My df is now unable to drive due to some health issues.
He has an appointment today and has asked me to collect him and drop him home again.
All I've asked is that he rings me when he's done so I know when to collect him - his appointment could last anything from 10minutes to an hour (he doesn't know till he gets in there as dentist isn't sure the problem yet).
He said he expected me to wait on the roadside (no parking nearby) and will not be ringing me. 
I don't want to wait on the roadside for up to an hour, I'm signed off work and would like to be at home in bed.
AIBU to him to call me when he's done?
