She tolerates you infidel only as much as her job requires. She is probably really helpful to other Muslims and thus seems to be doing a great job.  Management  knows they will be sued for MILLIONS if they fire her for any reason just short of outright criminal behavior.  The same happened to me at Pearson when I asked a Muslima information clerk how to get to the discount parking garage. 
" Just read the signs" 
"I did. I don't see the discount parking lots listed anywhere "
 "Well what do you want me to do about that?"
" Tell me how to get to it?" 
"It is not on Pearson airport property. It is not my responsibility"
" But there is a shuttle to it.  Which shuttle do i take?"
" That is not my responsibility".
