Rich's Burgers-N-Grub

It is one of the restaurant which I highly respected. But today they lost all the respect which I had for them. It is a incident involving a veg burger being exchanged with a non-veg burger. I would have stayed calm and thought this was an honest mistake if the place had been filled with people but the place was all empty and the employee were free. A employee took my order reconfirmed with me twice, I told him I do not eat meat nor I want in my order. He was yes the dish order is a veg one "Beyond veggie patty". He look at my order and start to prepare. And then served me a different patty one with meat. Thinking point here is that the people working here does not care about you or your order. They will make anything that comes in their mind and won't be apologetic about it. Even after confronting the employee about the order misplace the whole team was unmoved nor did they think about my religious belief which I belief. It was a very casual response from their manager stating either we can remake your order or refund you money. It would be understandable to an extent if the restaurant was busy but I was the only person sitting there. The employee who took my order was the one who made my order also. How can a person be so absent minded that they forget what the customer has ordered. I think it was all done on purpose as the employee smirked when I asked him if the order you gave me has meat or not. Does business really work on this mentality that money can solve problem and move on. It is a question from us whether this have been repeated and they have let it pass by refunding customer their money and reordering the food. The same person will show you an eye if we do not leave a tip when we place an order and will treat you like a highness while you fill out the tip amount. But after all the tip filling, it is normal for them and do what ever they want like the incident that happened with me.
