at the house I sold, I tapped into the wall outlet for the microwave since I didnt run a line. on its own, if you had the toaster on and tried to microwave something it tripped every time with a 20 amp breaker. So had to plug the toaster in elsewhere.... here at my parents I added additional outlets as there were only 2 in the kitchen, now they have GFCI around the sink, with 3 additional on the counter area, as well as the 2 others ( fridge and another wall outlet on the other side of the room.
The GFCI are on a line, the 3 additionals are on their own line , so if anything trips, there has to be some major draw on those lines... I look at safety first...
