Steak 'n Shake Enterprises — employees

We went to the Steak-N-Shake#03 Sunrise FL for the first time and and we ordered takeout the cashier was very unpolite and had an attitude. Then they made us wait 25 minutes for our meal and we werent the only ones who was upset, other people too. Im from Puerto Rico and me and my family told each other that we wont come back to this location again and we would tell other people not to come as well it was awful. I came here few years ago and i enjoyed it and i brought my family to enjoy it too but we all left with an awful experience.
