I just went through the line at the local grocery store.

After my check handled each and every one of my items, he told me he had just used hand sanitizer.

Prompted to ask “why,” I gave in and asked. He told me he had a wicked cold, but that I shouldn’t worry, because he has the strongest immune system of anyone in his family.

It’s amazing the things we do in the name of being polite and not being rude or making someone feel bad.

In this case, not just walking away and saying I’ll get these items later was my concession to his feelings.
