Is it normal to donate clothes to good will even if they have shit stains?

I stopped at a Taco Bell while on a business trip a couple years ago. I ate about five tacos for dinner and then got back in my car to continue driving on the highway. The tacos were especially greasy that day and about 30 minutes later my stomach started to hurt and I could tell that I was going to need to stop to go diarrhea soon. However, I was out in the middle of nowhere and there were no rest stops or gas stations in sight. So I kept driving hoping I would soon find a place with a public restroom.

Unfortunately, I wasn't able to locate a rest stop in time and accidentally shit my jeans. I was wearing dark blue jeans at the time and diarrhea soaked right through them. The interior of the car smelled terrible so I stopped at the next rest stop and changed into some clean clothes that I happened to have in the suitcase in my trunk. I also tried to wipe the diarrhea juice off my faux leather seats as best as I could. I subsequently placed newspapers on the driver's side seat and sat on the newspapers for the rest of the ride home.

When I arrived home I got out a garden hose and hosed down the interior of the car with water and placed several air fresheners inside to overcome the shit smell. Eventually the smell went away after a couple weeks and nobody can tell that the car had shit on the seat.

I washed the jeans in my washing machine but the shit stain would not come completely out although it did fade a little bit - there is still a noticeable dark stain in the seat of the jeans. So with tax season coming up that year I decided to donate the jeans to Good Will so that a needy family can have them. I used this donation as a tax write-off to offset my income that year!

Is it normal to donate shit-stained clothes to the needy?
