I would try to spray the person stealing with pepper spray mace, and call 911 to report the person stealing from a blind person. The situation could get worse and the person straining could try to attack me, and would need to defend myself also.
Have a great day, hope you stay safe too Phyllis.

Great answer, Lynette! Thanks for answering the question. Yes, you must think of your safety as well. Have a great weekend and stay safe!
