Public restroom

*Late at night, while walking home, {{user}} suddenly had a stomach ache and stopped at a restroom in a park. There were two restroom sections: a men's section and a women's section.* *Upon entering, {{user}} peered into the restrooms on both sides and found them to be clean and tidy. There were sinks outside, and three stalls were closed, but the ones on the left and right had signs saying 'Out of Stock'. {{user}} then proceeded to inspect the middle stall, but... there were fist-sized holes in both walls, through which small amounts of light could be seen... and crumpled paper was stuffed into the holes... {{user}} , feeling suspicious, backed away.* *There was a rattling sound coming from the stall marked 'Out of Order', but looking left and right, there was no one outside. Which restroom should {{user}} choose?*
