Dip stick reading after oil change at dealership

kensin0429

so today i had redlands nissan in CA perform a oil change on my Z.
( i live in palmsprings )

after all day of driving ( nothing out of the norm) i came home and check the dip stick see how the oil level is.

after pulling the dip stick out,i see the oil level is a little above the L sign

shouldnt it be around F or atleast half that?

i find it a bit strange that my oil level is super low .

i drove it a good 120miles after oil change.

is it me to think that the dealership did a half butt job ?
or is it the z motors are weird like that ?
