My 2 cents here (disclaimer: I’ve known and been a colleague and friend of Mike’s for a while now)
Yes, it can be understandably disconcerting for someone to hear yelling for any reason, especially in a dining establishment (worked for Gordon Ramsay though). I suspect you would not hear something similar at Grappa’s (I did witness a near brawl at Mandolino’s a couple months back though between chef and waiter, hilarious). If your looking for quiet controlled date dinning, shell out some cash, impress your lady, and go to Grappa’s or Parador. You want a place that’s fun and has personality, go to Mike’s and lighten up.
Two, Mike’s is not Foxconn. If his staff doesn’t like the work environment, they are free to go. As far as I know, none of his staff has been thrown jumped from a roof.
Why do they stay? He pays them well and treats them fairly, in exchange for dealing with a temper-tantrum or two every now and then.
Alternatively, you could choose an establishment whose employees who are voluntold to take Christian fundamentalist indoctrination cultural sensitivity training.
