​A company that offers pay by the hour lockers on public beaches.

Recently travelled south east Asia. Wasn’t comfortable leaving my stuff. Phone. Passport. Money etc when I went for a dip in the ocean. Do you think this would be a viable business? I have extensive experience importing for a business (100 employees in 3 Canadian provinces) I retired 2 years ago and have been travelling lots and am a bit bored. I think minicipal contracts would be the best
