Closing the Distance

I rushed to open the door and found the delivery boy standing outside, looking utterly bored. 

"Hi, sorry for taking so much time. How much is it?" I asked. I heard Sebastian's footsteps approaching me and looked over my shoulder. "What?" I asked, perplexed. 

"I am paying," he informed me. "How much is it?" he asked again with a smile on his face. The boy looked up and said the amount. Sebastian pulled out his wallet and paid for the food. I took the packet from the man and smiled.

"Thanks for the tip, man. Have a great time with your girl!" he cheered and giddily walked away. I turned to glare at Sebastian. 

"Why didn't you let me pay?" I asked him seriously.
