My parents came to visit me last year via New Delhi airport. They had to stay in a hotel overnight because of one night layover, hence, had to check out the luggage and check them back in the next day. The gentleman who puts the tape around the suitcases , showing that it has been inspected, after passing through security offered to put extra tape to make it even more secure for couple hundred rupees chai-samosa expense. My parents politely declined. He went away. No problem.
