Let someone go first

I let a woman at Walgreens go ahead of me since she only had two items and I had ten. Her card wouldn't go through and there were issues and she ended up taking forever at the counter. Normally, this would have irritated me as I am usually in a hurry but she kept looking back and apologizing and I didn't feel bad at all that I had let her go ahead of me. I just smiled and continued to wait. I don't think the five people in line behind me were too happy but hopefully they will find this site as well.
