Dunkin' Donuts

I was at the above location and went through the drive thru to order 2 coffees. I told the drive thru attendant that I needed a Large Hazelnut Light and Sweet and a Large Hazelnut Black with 3 Equal. The man stated back to me that I wanted a Large Hazelnut Light and Sweet and a Large Regular, to which I replied, no the second one should be black with 3 Equal, Hazelnut. So he said, Ok, Large Hazelnut Light and Sweet and a Large Regular Black with 3 Equal. At this point I'm getting very irritated and I said, NO, they are both Hazelnut and he yells back I GOT IT, LARGE HAZELNUT LIGHT AND SWEET AND LARGE REGULAR BLACK 3 EQUAL! ANYTHING ELSE? When I got to the register I was infuriated but he was not the person working the register so I couldn't say anything to him, and I had to get back to work. But he did make a point of glarring at me through the window when he brough up my coffees. I should mention that this man did not speak English well, so I doubt he thought he was saying anything wrong. But I should not be yelled at because he doesn't speak English properly. I think he needs a recap of Customer Service. I will not be going to this location again.
