Moe's Southwest Grill review: queso/customer service

For starters they never say "Welcome to Moe's" when you enter but I love their queso so I keep coming back. So today was supposed to be free queso day, 9/19/19. The owner of this location was actually the one who told me to come in on this day a few weeks ago when I was there. So I entered with my son and asked for 2 cups of queso. Just as the worker was finishing up my order the owner comes out the back says 1 cup of queso right? I said no 1 for me and 1 for my son. She told me no only one! I said it's one per person we're not 1 person it's 2 of us and besides my son eats a cup by himself. I also mentioned that I come here all the time and reminded her that she was the one that told me to come in on this day for the free queso! Finally she said ok. I was so appalled! They didn't even fill the cup, only filled it halfway. So finally we get home and start to eat the queso and it was so loose like it was watered down! It the same queso you would receive if it wasn't free! I'm so disappointed Abdul relieved that I didn't spend my money on that garbage!
