The White Carpet

I am tailgating at a football game. My friend L. gives me two unalcaholic drinks that are "bad" in some way, either he spit in them or something got in them. I then leave and find myself at another friend's house. I don't know this person quite as well. He is older and I have no real life connection for this DC. I start loading up a plate of steak, beans etc. from the grill outside when I spill my coke a little bit. It lands on a piece of white carpet near the sliding door outside. He is quite upset and cleans it up right away. I go in & see a salad at the table that I was going to eat for dinner. Some girl is invited over and she comes in and sits on the couch. Again, I have no connection w/ this DC. I go to fill up my drink and this time I spill the whole thing. He gets extremely mad and says "This is ridiculous!" I try to help but he claims that I am making it worse. I then get ready to leave by saying I have a paper to write and begin to exit the sliding door with a full plate of food. He tells me that my friend L. can come over whenever he wants. He calls him "Dr. L" He clearly doesn't like me at all. I open the sliding door and my hand holding the food wobbles slightly and half of my food ends up on the deck....not on the carpet. His dog happily eats it up. The man laughs and I spill the other half leaving only a fork full of beans. He says "at least ya got your beans" I leave and realize that I still have his dishes. END
