No problem, good luck! 

thanks.
i just some curious,y use eight-six,not seventy-six or others.And now i know it came from the bars.Thanks for your help.

 yes, to 86 someone means to "cut them off".   I think it started as a slang word in bars- "He has had to much to drink, he is eighty-sixed."  It is now used to describe stop service to anyone in almost any scenario.  Mainly used in the service industry.
Hope that helps
