White Castle review: customer service complaint

I pulled up to the pick up window realized I forgot a 5 pc cheese sticks asked to add it to my order. The cashier Jaylen acted annoyed and came back and said the manager Bobby said I could not add the item and had to go thru the line again. I was shocked by this terrible customer service and very rude! When I did go around to wait and order again the cashier stated it would be a 15 minute wait! Really! Left me sitting there until I honked my horn then she finally took my order! When I came around to the pick up window window they sent a guy up with my order neither would face me again cowards! Do not want anything free or any coupons just want a response in how your gonna correct this terrible service or I will take my business elsewhere!
