Does leaving a refrigerator door opened for about 20 seconds actually use up a large enough amount of energy/ power to consider not leaving it open for that long? askscience

I'm at my parent's house, and they think that when I open the fridge and leave it open its a huge waste in energy.

I'll open it up and grab some iced tea or something, walk over to the table to pour it, and put it back in the fridge. It takes like 20 seconds, tops. Is enough energy or power being wasted here to actually be mindful of leaving the door opened?
