The greedy friend missed a soda

I went to a party with my best friend whom i studied with in senior 4.When we reached at the party, we were warmly  welcomed and we were given seats in one corner  of the tent.While we were seated, people brought in crates of sodas and put them on the other side of the tent.The crates were very few and they could not serve us all.My friend told me that we should change the seats such that we could get the soda.I told him that i could not change but he insisted.He changed the seat and sat near the crates of soda. As soon as he had sat near the crates, the servers changed the decision and decided to start from the other side on which i was sitting,because there were important guests. They served us sodas and the other friend of mine could not change again to join our side.
