Great friends showed up for dinner at Marinelli 's first . Colleen , Tim & Nik , Stone & MC made were all there . After eating and chilling at the restaurant for a bit we headed over to the bar . We got a good spot blocked off and saved an extra 3 chairs for those who did n't make it to dinner . The band started about 10 pm , but prior to that both Matt and I each started out with a " boomba " a 32 oz beer .

Give answer the following question using evidence from the above passage: Why did they save extra chairs ?
For their friends who were coming .
