why are they allowed to continuously serve cold food thats been sitting for hours and disrespect there customers with awful attitudes with no consequences?

There's always allot of people waiting and service "seems" slow because the food is cooked AS IT IS ordered, during the day anyhow. Maybe your food got cold quickly because it you ordered to go yesterday and the temps were so cold. It's not a home cooked meal that's been in the oven all day so just as quick as it received heat it also loses it. Basic science.

Dont know. The core employee base there are a bunch of punk HS kids. You can see it in the dedicated managers faces they want to slap the hell out of them. As for your solution, call the owner or corporate
