I knew someone in college who would buy new clothing, wear if for a couple months and then reattach the tags and take it to the store and get a full refund. My sister worked at a mall in the 1990s and said this sort of thing was common. So, some of us are purchasing new clothing that should actually be going to a thrift store. Additionally, I know people who just love to impulse shop--and then they never wear the items they buy. They donate the unworn items, tags still on, to the thrift store or send it in to an online consignment shop.
Whenever I buy new clothing, I assume there’s a good chance at least one other person has tried them on. I have no idea whether they had body odor, sweaty feet, or how long they were wearing the item in the dressing room that I'm about to purchase.
When I stay in a hotel, I try to not think about how many strangers have slept in the bed, used the towels, or laid on the mattress before me---otherwise the ick factor sets in.
The same goes for restaurants. I try not to think about how many people have eaten off the same plates, used the same utensils, or wiped their mouths with the same cloth napkins. Many of them I'm sure probably were sick with something when they were eating.
Movie theater seating--how many strangers were sitting in the used seat before me? How clean were they? And were they feeling sick at the last showing?
Once you see it, you can’t unsee it.
