I used to stay in really cheap rooms when traveling around. I would get these foam mattresses (no springs) that had a towel for a blanket and no upper sheet.
Guests slept with a towel for a blanket. The towel, pillow case and fitted sheet usually had some kind of cheesy cartoon on it or weird pink or bright blue colors like ones sold in China for children ????.
I even remember having to discard a grungy small dirty pillow that I did not want my face on and use a towel from the bathroom, or my pants to stuff in a pillow case instead.
In one place a large roach (I think a water roach) was on my pants in the main room and I flicked it off. Later that night hours later it crawled onto the bed and bit me on the back while I was sleeping. I'm sure it was the same bug I had flicked off earlier. ???? Of course, I did not hurt it, just put it out the window. ????♂️
