I don't expect a Michelin 4 star dining experience at a fast food place, but getting the basics right is expected. The new Dunkin Donuts in my neighborhood can't seem to get drive through orders right..wrong quantity, missing items, wrong donuts...arrrgghhhh.
Alas, even more expensive restaurants are prone to issues. Went to a nice restaurant for dinner Friday night (local place that's about $50 each with wine)...appetiZers came out after entrees, one entree was undercooked/raw, etc. frustrating....
