What body language tells you a negotiation is going terribly?
Crossed legs are a very bad sign.
Crossed legs can have a devastating effect on a negotiation. In How to Read a Person Like a Book, authors Gerard I. Nierenberg and Henry H. Calero reported that the number of times settlements were reached increased greatly when both negotiators had uncrossed their legs. In fact, they found that out of two thousand videotaped transactions, not one resulted in a settlement when even one of the negotiators had his or her legs crossed.
