Steak 'n Shake review: service

On 23 Jan 2019, at about 1929 I left the Steak'n Shake (7101 West Colonial Drive, Orlando, FL 32818) because I'd been waiting since 1908 for my order. The to-go order was 2 triple cheeseburgers with fries and was cooked by 1908 (shortly after I ordered them). The cook placed them for the next man to put the condiments and vegetables on... but there they sat while the second man waited on everyone else's orders (even those that came in after me). I estimated that after over 20 minutes, my burgers would be a bit cool, if not cold, and the man could see me as I was at the counter waiting for them.
Also, I don't know if is was to do with me or not, but he seemed to be laughing a bit when he looked my way. That could have been a coincidence, even as I was white and those that were being waited on before me were not, even as he was not. Again, this might have been coincidence, and it might not have been. I just know that after 20 minutes waiting for burgers that were just left to sit there after being cooked, I was not about to take them.
I told the cashier that I didn't want them any more, explained why and asked for my money back. After that, I traveled a bit further to go to a Burger King. My daughter was feeling ill and wanted the triple cheeseburgers from Steak'n Shake, but after I explained, she opted for the double Whopper instead. If this is the level of service, I believe I will continue to go elsewhere. I am usually patient, but this was most apparently deliberate on the employee's part (again, not the cook).
