There is a contradiction though, as you say the battery was fully charged, yet the recovery guy jump started you?

This suggests there is a problem with the battery charging!

It all depends how the test was done, but if that draw was performed as how you would leave the car something is not right!

If you think there is a draw the easiest way to go about it is by process of elimination, remove fuses and note the circuit that affects the reading.
