I had this idea a number of years back but I read in a New York paper that it had already been invented and the fellow was arrested.   He was selling a universal hanger for $1.00 When you sent your dollar to P.O. Box such and such he would send you a 3 inch nail. I thought it was a great idea.
On a more serious note someone besides me should come up with a small gadget so women could put in their purse and when they go to a public washroom they can take it out and it would have a suction cup on it then placed at a convenient spot on the washroom wall so they could hang their purse on it. I'm told that women do not like to hang their purses on door hooks in stalls as they are to close to the top and someone can easily reach over and grab it an run.
