Had an oil/filter service on my 2014 non Z51 base C7. Instructed the Tech to add only 6.5 qts. I planned to add the other .5 qt at home the next day after checking dipstick reading. Much to my surprise the dipstick showed full. Is this a normal reading with 6.5 qts. Manual calls for 7qts with filter.

I change my own oil and have noticed the same thing.
What that generally means is that a tech didn't allow enough time to completely drain the system before refilling. It's only a potential issue if it causes it to be overfilled.
That's one of the reasons I am insistent that the service dept. only fill w/ 9qts. instead of the recommended 10qts. on my dry sump LT1.

it was draining for about 5 minutes. Difficult to believe .5 qt left.
Is the OP sure they changed the filter? Was the car at the optimal angle to drain (did they jack it up on one side)?
FWIW, overfilling is not nearly the concern for wet-sump cars as it is dry-sump cars. Not saying it's optimal to overfill by .5 qt. for most driving, but it certainly won't cause problems in the short term, unlike overfilling a dry-sump can cause almost immediately.
Wet sump or dry, it still takes more than 5 minutes for ALL of the oil to drain from all the nooks and crannies of the engine back to the oil pan. The drain angle is also a factor.

Service was performed over a pit (not jiffy lub or any outfit like that)

The 2014 Service Manual clearly says the volume chart is only an estimate and that the level is the key and must be checked. In my dry sump I use about 1/4 to 3/8 quart less than the volume indicated (not counting the 1/2 quart under max that I intentionally set the level.) Some is no doubt left in lines, rocker arms etc. I wait ~10 minutes and little if any oil is dripping from the two plugs. I also heat up the oil before draining, something a dealer's mechanics helper may not do. Have done all my own changes in 3+ years with the rear jacked as well as the front!
I have always used level NOT a volume estimate in the 50+ years I have been changing my own oil! In a dry sump that requires running the engine to get the oil hot, then waiting 5 minutes after the engine is shut off but not more than 10 (so oil that drains back to the pan isn't excessive causing a false low reading.) That is more time than some mechanic's helper operating the oil change bay will take!
Side Bar: When I assembled the 502/502 create motor for my street rod I encountered a "Catch 22" in regard to estimated oil quantity! The Chevy instructions did NOT provide a oil volume estimate! They said fill to the level indicated on the dip stick. I have long tube headers and the metal dip stick provided with the engine would not fit! I bought a Lokar dipstick that had a small round billet aluminum **** and a nylon dipstick that you cut and fit to the to the max level desired! Had to cut off the metal handle on the supplied dip stick, bend it to insert and use needle nose pliers to pull it out to check the oil level! Then measured and fit the Lokar dipstick!
When changing oil, some residual will be left in the engine. Rocker arms and top of the cylinder head are some spots.
