not terribly expensive at all, which was unexpected
Well Luke is a casual restaurant. So it really becomes blurry as to what is proper service. You would probably find it annoying for an upscale restaurant to ask you to keep your dirty silverware for entrees/dessert/etc.. but you'd be shocked if a place like Sammy's took your silverware (even unused) away like a nice restaurant does. Luke isn't podunk like Sammy's.. but it's certainly considered a casual restaurant in New Orleans. Shorts are even accepted.
Not to by any means defend your poor service, but it sounds like your server as a general person was just awkward and doesn't think about what he's doing when you're referencing the bad joke and beer glass situation. I will never understand why restaurants hire people like that/don't train them better.
I went through a 2-3 week period where I was "test running" at work to be hired. And if I didn't do well with the customers, I would have been let go. We still do that with new hires. More restaurants should do it.
