When I was 14 (about 12 years ago) I worked at a donut shop that my mother had worked at I got in trouble in school and started working there.
I seen to men walk in an older guy and a 20-30ish year old dressed in shortalls with lots of primary colors including a hat. I think he had a fanny pack on. At first I thought nothing of it and knew nothing about infantilism and I never touched internet yet. I thought I was a freak. Being young I laughed in my mind asking why is he wearing that. The place also cooked mini burgers like White Castle and that's what they ordered. I started cooking them. (The place was like a bar with stools and the grill was on other side of counter. Kinda like Waffle House.
They asked to use the bathroom which was in the back and had to go outside to the back of building and open the door to let them in the back door that were right next to the bathrooms. Another door seperating the bathrooms from the baking area. I let them in and went back to cooking burgers. They were back there for a long time. I finished cooking them and put it on trays. It must of been 10-15 minutes til they came out. When they finally came back in they ate, paid, and left.
Well I needed the restroom sometime later and went in and did my business and washed my hands dried my hands off with a paper towel. I went to throw it away and I froze up as I seen a diaper. It wasn't balled up and it was messy and wet. I thought it looked big for baby siaper. I took some fresh paper towels and grabbed the ends of the diaper and took it out. The mess didn't stink at all. (Sorry for rough graphics but...) It was soft filled from back to front and the diaper was quite thick too. It had been stuffed with an undergarnment pad without the straps. The diaper was White with Blue tape tabs.
Not too long after this I finally got the internet and my whole world changed. I found DPF!
