It is not at all unusual for restaurant cooks and front of house folks to interact and trade stories and techniques after hours. When I cooked, we often ended up at a local all night diner eating and talking shop. I can't count the number of times I have been in a bar or restaurant and met a cook from another restaurant, hanging out, sometimes even trading shifts in a new kitchen.
I can't speak to everywhere, but, in Oakland and San Francisco, it is rather common for folks to socialize within the restaurant trade. And in my real profession, as a landscape architect and irrigation designer, there have been many times my competitors and I have helped each other out.
On edit to a different point, I will note that BBQ is one of those things, everyone is an expert. There are two shops in Oakland, that I consider to be quite good, several friends of mine hate them both, one even said she left her food and spit out her first bite, it was so bad. These folks love, love, love a place that I will not visit, I gave their favorite place two tries, first time they sold me garbage brisket, chopped mush, the second time, shiner ribs. When I mentioned it, the owner came out and said he was "sorry, but, if I didn't know good BBQ, it wasn't something he could fix" and "ribs bones showing is normal"
