I guess someone was tired of working or hates their job. Although i browsed other reviews,looks like poor management is the issue. Ive applied here several times and no luck even though i fit the requirements.
On 5/22/25, i went around midnight to get some food for the fam.
I guess 10 sliders was too much for whoever was cooking to handle. They had each one covered in onions. Im not exaggerating, could hardly see the burger patty itself when you take the tops...

This location has always impressed me with the quality of food! Always hot and fresh! Sometimes the drive thru can be a bit busy but I don't mind the wait for the hot fresh food they deliver!
Also their breakfast is really frickin good!
Big shout out to their employees that make it consistently great!
