Manager terrible service and menu lacking quantity instead pinning it on the disclaimer

Manager by the name of Andre has disgusting customer service. Went as far as telling us that we are making a big deal out of a small thing and that where can we imagine getting 3pieces of meat for that price. What you order from the menu versus what you get is completely different and the first manager ddnt even know the disclaimer and had to check at the back of the menu. The menu should clearly stipulate the quantity and number of what it is you have ordered
