Burger King review: complaining about rude manager at drive thru

I order in drive through and I was trying to inform employees that I had a coupon but she cut me off and said pull around.
I'm at window she tells me next time I have a coupon to let her know. So I told her I was trying to but you cut me off an said pull around front I told again she got loud with voice and got loud back with her she closed the drive through window on me and kept my coupon so I pull off I wasn't going to spend my money with a mean rude employee so I pull off. Maybe that location needs a lesson and trading in customer is always right and maybe start hiring African Americans I been to that location 4 times and never seen a black person working there all Mexicans which is unfair to race we need jobs just like they do.
