That short break is just about the right amount of time to make a batch of microwave popcorn - not the prepackaged kind but with kernels in my special microwave popcorn bowl.
Nicely topped with butter (not margarine) and one of my preferred seasoning powders - usually white cheddar but ketchup is pretty darn good as well.
Otherwise, bathroom break, mini tasks, browsing web or checking emails or playing my cash tables.
