Shopkeeper allowing one to take items and put the money in the till
Q: I work as a teacher at a Madrasah. The Madrasah has a tuckshop. When I buy from the tuckshop, the shopkeeper (an elderly Moulana) allows me to take what I want to buy and pay the money directly to the till. In fact, he told me to do this once or twice. There is no loss to the tuckshop in my doing this. Generally, the shopkeeper doesn't even know what I bought since I paid directly to the till. Is this permissible?
