Steak 'n Shake review: drive thru service from 8:30-9:10. long wait & rude employee

I did not appreciate the service I received by the young lady working the drive thru this evening October 12 from 8:30-9:10p.m. I was asking how big the chili bowl is and she couldn't tell me how big it was. She was talking about a cup for a dollar. I asked several times. Over the speaker I hear "they are taking forever." The wait was more than significant giving the time frame and only ordering two meals. She was rude when I came to the window and as I waited and waited I noticed her barely moving, walking or doing much to help the other gentlemen prepare. I felt bad for the people in front of me as their shakes had been sitting there since I pulled up. She had touched them but didn't do anything with them. The manager in the blue shirt looked like he was actually trying to get the job done. She told me again not very nicely to pull forward. After a signifant wait then too she came brought me my food and handed it to me as she walked away. No comment, nothing. Her customer service was terrible, my order was wrong- I ordered a reg. Cheeseburger no onion and I got a bacon cheeseburger with onion and there was no reason for the wait or for her to be rude over the speaker.
