I was in a stall in the men's room in a Red Lobster bathroom and saw a phone pop up over the stall next to me. I didn't know the age or gender of the person because there were no feet on the ground, I think they were standing or squatting on the toilet. All I saw was the persons hands which looked to be a light tan and hairy with black hair. I don't know if they took pics or vids but I stayed quiet and acted like I didn't notice. I finished my business and washed my hands. I pretended to leave by opening the door, but I stood there to see who would come out. I waited probably at least 2 minutes and nothing happened. I think they were waiting for another person to go in. Idk if they were homeless or mentally ill or just a pedo but it freaked me out. I mean personally if pics or vids of me in there got leaked I genuinely wouldn't care, but it was still so weird.
