Steak 'n Shake review: milkshake and salad

Served a warm milkshake to me and when I asked if they culd make a new one their reply was well it's warm in the kitchen I can't guarantee it will be cold the next time so needless to say we did not get another but the salad I was served was wilted and slimy also and when I told the waitress she simply said ok and was not very friendly or nice at all.. The whole experience was t very pleasant at all and nobody else during our visit seemed very happy.
