Did your partner also signal OOB on lines that weren't his responsibility? I have had this happen to me repeatedly by lesser and more experienced partners this season.
That alone ticks me off more than anything...and not a whole lot ticks me off when it comes to the partners I work with.
I thought about putting this in a separate thread, but, it's too petty IMO.
Thanks for providing a place for me to use as a forum to vent a pet peeve.
edit: thanks snaqwells
