of course, your vehicle has to be reliable, presentable & in a roadworthy condition.

i know guys who make friends with the people at the stores or warehouses and they have their own agreement like this:
i can do whatever other work i have until theres enough deliveries accumulated for a full load

then i come there, load up & once ive delivered the stuff, im done for the day.

obviously, if they are very busy, u have to hang around- but u get paid so its not like youre wasting time.
