I could not leave it lying around just like that as I am not assured of the safety of my belongings . I noticed that there were unoccupied lockers . With all the reasoning ability that the almighty has bestowed on me , I decided to shove the plastic bag inside one of them and have a quick bath and come before that particular locker could be assigned to anyone ( the keys have to be collected at the desk that was just outside gym which was a little far away from the men 's room . Since I was clothed in a towel I decided against such an expedition and took the quick way out or in as the case may be ) .
