Not following instructions and interrupting.

50 year old blokes unable to navigate the 6 yards to
my front door because they are too distracted and nervous.
I told him to turn his volume up.
Then discovered he was actually peering down the road, like
a twitchy meercat.....not walking.
Had to turn my phone off, abandon this little puppy
and he was replaced by a 30 yr old male with a sense
of direction within 15 minutes.
Am I doing something wrong?
