Cheap Guy

Among our friends, one of them is so so cheap. I've never seen any one like him. We supposed to have BBQ this Saturday ( July 4th). I am the organizer so I sent the invitation to each family for the food preparation to the BBQ. One of the guys, he supposed to prepare burger. As soon as he received the invitation, he told me to take care the veggies, bread and ketchup for him, he will only bring the burger ( ground beef). Besieds that, he asked if I could get him the ground beef from Costco... WTF, it means I take care everything for him and he just bring his wife and 2 kids to the party. And one thing made me very pissed off was he invited another family without telling us and split the bill with him. In other word, he just bring burger and can have someone to share the cost with him. After I found out he's so cheap, I told him I won't help him to get anything, he takes care his own part. And we decided to split the bills at the end of the BBQ. I know there's some cheap ppl around us, but never thought would be " that cheap"
