Spouse and I have a discussion on what to do after you pour a sauce out of a glass bottle. I do nothing but my wife takes her finger and wipes the excess from the bottle before she puts the lid back on. I think touching the food is disgusting and she thinks leaving it there to gum up the lid is disgusting. What do people do?
Your way is messy, her way is unsanitary. Use something clean to wipe it off.
