BAD service

Very bad service We have ordered online and was said our order would be ready in 30 Mi****** we arrived after 30 Min we was told to stand in line (very long line) where everyone is ordering.We tried to explain we have already ordered and just want to pick up our order.The staff said it doest matter we must stand in line. WHAT IS THE POINT OF ORDERING ONLINE And we were treated with no respect the staff was very rude. Last time Romans seeing me
