Dunkin' Donuts

My fiancé and I went to the mall to grab dinner from Panda Express. I went over to this Dunkin Donuts at approximately 8:40pm, definitely before 9pm because no other food place had closed. I walked up to the register, there was no one at the counter and it said "register closed". The Latino kid who worked there came from around the corner, must've been at another store, and I asked him "Are you guys closed already?" Mind you, it's not 9pm, yet, but I ask anyway. He says, "Yeah, we're closed." I get drinks from the restaurant next door. In the meantime, he's at the register playing on his phone. 10 minutes later, two Latino men and a woman goes to the register and receives service - maybe I didn't look "Hispanic enough". He had the nerve to keep looking at us while we ate. I will never go to this Dunkin again and tomorrow I will be calling the store manager.
