McDonald's

Horrible service, they where under construction, I went through the drive thru window to order 2 banana smoothies and one frappe, the guy who took my order heard one smoothie, or was not paying attention when I ordered. when I go to pay they only charged one banana smoothie and one frappe I pull up to the second window, where this older women, around her 50's African American was there she hands me the drinks and I tell her I ordered 2 smoothies only got charged with one, she became very threatening and extremely rude and unprofessional, acting like she wanted to fight me. I became very angry, and made sure to address with the corporate offices that are in charge of the mcdonalds in this area. They assured me they would directly address this with that specific employee although they where all unprofessional, they need to really check who they hire. Disappointing service.
