OP here, let me just further clarify a few things. I was sincerely hoping for this not to become a thread assessing whether or not we were getting our undies in a bundy over something minor. Quality of service is perceived, and that is why I chose not to list out each issue we had...I didn't want the controversy of determining whether a trouble was significant. I've read threads about people saying you should never reduce a tip, just don't go over the recommended if the service wasn't up to par and I wondered what most people would do. It's after the fact so I guess it doesn't matter anyway, and we are highly unlikely to experience poor service again...it's very rare on DCL! Just the place-setting/high-chair incident would likely not have phased me. Anyone can have a bad day!
In the end, no more plates were broken and my husband walked in first to remove the place-setting and I put the baby in the high-chair while holding his legs to physically keep the server from grabbing them. It worked out. But my shellfish-allergic husband (allergy noted) being served shrimp (which he didn't order) twice? And the server asking if he'd be okay with that or if he needed his meal replaced? That is simply odd, they are trained better than that! My point is, it wasn't one issue...it was the whole 7 days and it was the other tables they were responsible for as well. Anyway, we've done DCL before and had an idea of what to expect, and we were disappointed with our servers. Simple enough, everyone is entitled to feel as they do. I appreciate your help in determining that we could have asked to be moved and a reduction in tip is okay if necessary. No need to re-hash it now, let's move on!
