You are in the sauna and have paired up with the cutest guy there. You reach for the lube dispenser in the room prior to a hot hour or so. In this case, though, "hot" would have been the operative word, unfortunately. Some 62-year old crazy jerk in Sydney filled a dispenser in Sydney's Aarows gay and bi- sex ciub with hydrochloric acid! Thankfully the room had been fitted with tampering alarms and the acid was discovered before anyone attempted to use the dispenser.
