Firstly - rarely checking a flight control surface is gash.
Secondly - if the flaps don't retract, there is a problem. Do you really want to mess with safety? Let me get this straight, you are condoning not checking flaps as per POH by lowering them fully just incase they don't raise again and you can't fly?
You're right of course, it's sloppy and sticking to the POH is best practice.
