There are lockers for users to put their personal belongings and food items which cannot be brought into the library.
He saw a pair of shoes placed tilted against the wall inside one of the lockers. There was also a pair of shoe insole taken out of the shoes and placed in front of the shoes. There was a pair of socks in the locker next to this one.
He guessed that the shoes, insole and socks were wet due to the rain.
Someone just left them in the locker to dry.
He couldn't imagine how smelly the locker would be and wondered why the security guard allowed it.
He asked the security guard, "Do you allow people to leave their shoes inside the locker? The whole locker would get so smelly."
The guy replied, "Never mind, let him put. If I stop him and he complains to management, I will get it."
