The worst people I have seen in the business. I asked the hostess to substitute a veggie Patty in the 4 cheese burger and she her to make sure that there was no meat in it. She took like half an hour to check if they could even make it like that. I mean what the ****! And then when I get my Burger, there was no patty in it....! What the **** ! So, I go back to the hostess and I was like where is the patty...? She is like you said no meat. I was like yeah... That's why I asked you to sub a veggie patty. And her response was gold. She said that they consider ALL the patty to be meat. And the worst part is that they were all laughing at me for wanting a 4 cheese burger with veggie patty...! I didn't want to create a scene... But these people need to respect the customers... The stupid ungrateful bunch of illiterate jerks....!
