Hey, here's an idea...what I'm keying in on as bad form is the interruption. Like I said earlier, short of an emergency, I prefer to just grin and bear anything I dislike until an appropriate moment comes to say something or excuse myself.
So,
medtran49, is there any way you can let the server know you already are familiar with the specials, instead of trampling on their routine? Something like:
"Hi! My name is Candy and I'll be your server tonight!"
Then, right in that pause before the next bit starts, you could say:
"Wonderful, Candy, thanks! And I've already seen the specials board, so I'm familiar with those."
That might be a nice compromise - you don't have to listen to the specials and the server doesn't have to feel like they've just been smacked down.
On a side note - quick internet search revealed an article along the lines of "What Your Server Wants You To Know," and number 2 on the list is...a request to please stop interrupting them when they're spitting out the list of specials.
Maybe we need a "What Your Dining Customer Wants You To Know," directed to the server!
