We open crates, we get nothing

I open a crate...I get a 10 cent pistol... open another one hoping to get somethig better... and i get another pistol... then another and another and another..
Then i say "F**K THIS S**T I WILL NEVER OPEN A CRATE AGAIN!"
5 minutes later i open another one.. i get an assault rifle that costs 1 dollar,
at least i get 1 dollar back...
