Like a lot of the crap in your body that is hurting you its not obvious until you get a health issue or cancer later and then noticeable statistically not individually EG you look at two populations and one had more folks with a much higher incidence of cancer or auto immune diseases or what have you. The fact that its not obvious doesn’t make it any less real. Those free bags were closer to free cigarettes.

I used to manage cashiers and handled 10s of thousands and observed more. Like any human beings they do occasionally make mistakes. If you haven’t noticed anyone EVER making a mistake ringing you up it means you don’t pay attention.

I don’t tell cashiers how they should bag things because that’s obnoxious but I do know that I do a better job of not putting fresh things with meat or things that are liable to be squished with canned food or all the non-food items together.

If you avoid 4 minutes waiting once per week and 2 minutes putting away things over your life you will save over 300 hours. You aren’t liable to be awake for much more than 100 hours a week so that is like 3 weeks of your life.
