Steak 'n Shake review: Can't buy food at steak n shake

I ate at one in dayton, OH and liked it so on my way home I saw it had one on the sign at the exit so I took it finally driving up and down the road it was down a side street. Finally got to order my 1st food at steak&shake, but no, there was 1 guy sitting at the drive through in front of me, so I pull up to order and the guy says it will be minimum 10 minutes it already took 15 min. to find it so I left. 2 weeks later when home in Lansing I went to Lowes and found another one with just 1 car in front of me. I thought yeah this will be quick. Not at steak&shake. I pull up to order and try to order and the guy says it will be 10-15 minutes so I order a #4 and the guy says it will be 10-15 minutes again. So I try and order my #4 again and he says 10-15 minutes again, so I say "what" 15 minutes before I can order (jokingly) and he says yes. So I asked how do you guys even have a business then drive off pissed and hating Steak&Shake and thinking I guess i'll never eat at a Steak&Shake ever again. I got on my computer to see why I can't order food at these places without having to wait at least who knows how long to eat. So all I can say about Steak&Shake is YOU SUCK!
