Terrible service

Had a very bad experience this morning. I wanted to take my mom and dad for breakfast, because it was my mom's birthday. My mom is a vegetarian. There was only one breakfast dish for her to choose from that's why I asked the waitress to find out if my mom can have the waffle with haloumi cheese. Not a difficult dish to make, I'm sure?????? The manager said that they can not make this for us, because the waffles are precooked. He said they freeze the waffles and then heat it up in the microwave. FROZEN waffles?????? Not made freshl?????. This is very bad!!!!!!! Afterwards you put on the extras......isn't it???? So just to put haloumi cheese on the frozen waffle isn't that hard?????????? Moses, the manager, was very rude. When we said we'll go somewhere else, he just turned around and walked away.
