Of course there is the obvious answer of comparing (let's say) Applebee's to The French Laundry, but I think I am asking something a bit differently.
Here's the scenario:
Two restaurants that are very similiar in price ($5 salads to $30 entrees) and atmosphere. I would say that the ambiance is casual bistro style, linen tablecloths, soft lighting and candles. Yet, the customers act differently in these similiar restaurants. Additionally, both of these establishments share the same clientele (who expect different types of service when dining). Here's an example: diner in restaurant #1 will keep silverware for next course but in restaurant #2 will request a new fork or knife. Is it because in rest#1 we dress casually (in rest#2 we dress in all black, with tie and bistro apron)?? I am not quite sure in the dynamics of it all. I usually bring fresh silverware anyhow, regardless if asked or not, but it has been quite interesting seeing how customers act when placed in different settings.
So overall, my question(s) are: Does your table etiquette change in accordance to atmosphere and restaurant type? Or does it stay constant no matter what? Do you see yourself expecting more (or less) from restaurants that are similiar but have different protocols?
