Been reading along, and now cannot help from chiming in...
The first time I went to Cali Grill, dressed nicely, I was appalled to see a family, also apparently waiting for a table, where the "lead male" was wearing cutoff denim shorts and a dirty (yes, actually visibly dirty) Dolphins jersey. And they were seated. This was many years ago, and I can't imagine it's gotten any better since then.
I've eaten at CG several times since, and have just put blinders on. I don't actively look at my fellow diners, but I guarantee you, if I saw "Dirty Dolphins Jersey" guy again (or anyone similarly en dishabille), I'd notice. And, sorry not sorry, would disapprove.
Honestly, the past couple times I've been there, I've been so preoccupied by the lack of excellent service, I didn't even notice the other diners.
