Regular tiffin delivery person familiar with the lifestyle of the customers

According to media reports, a tiffin delivery person Mahesh Beniwal stabbed a senior citizen Shamina Nakara in Gowalia Tank causing injuries. Shamina Nakara and her family were ordering tiffin regularly which were delivered by Mahesh Beniwal, who was residing in Palghar. Since ordered food is far more expensive compared to home cooked food, Beniwal thought the people ordering tiffin food were wealthy and would ask them for money.
A few days prior to the incident, Beniwal had asked Shamina for Rs 50000 which she refused.
So when he delivered the tiffin next, he asked for water and then followed her into the kitchen stabbing her
This shows the risk of having home delivery, especially if the same person is doing the delivery every time, they get information about the family who is their customer.
