Should I cover or move this outlet?
Current code in many places (ymmv since we don't know where you are) calls for GFCI outlets throughout a garage.

From a practical standpoint, a GFCI above the sink is recommended for safety, so I'd change it. (This assumes you don't have a gfci breaker or another outlet upstream that makes your sink outlet into a gfci.)

If you don't like the cord looping over your sink, be sure to get an appropriate extension cord. Look for a 15A rating and stay as short as possible. (These often get called "air conditioner extension cords".)
