Seems a good place to retell a story I heard from brother in law today, happened to him this week.
My brother in law was at uni., he is in a wheelchair and the bathrooms have automated doors. They take a while to close when opened. Was busy outside, market day in the courtyard next to bathroom. He went in and found two girls going for it, both naked, one with legs over the others shoulders. He was shocked ofc, just smiled said "door lock". As you can imagine the automated door both takes a long time to close, and stays open with anyone blocking it. Market day got more excitement than it expected. As you can imagine a crowd soon gathered to cheer the couple on.
Make sure whatever you plan PB, that you only get the audience you desire. :-D
