Lunchbox was with his family at a restaurant, and while they were waiting for their table, his kids were playing with the restaurant sign.
The letters on the sign were made of light bulbs, and his kid broke one of the bulbs! So he went inside to tell the employees what happened. He lectured the restaurant about it saying they needed to move their sign because kids are running around, and things can get broken, and the glass is very sharp and unsafe for kids. He did that in hopes of getting free food but all they did was thank him for the heads-up about the sign.
