So given you come into the door and the hostess is there, let her say her whole little "Welcome to (insert random restaurant here). How are ya'll doing today? How many are in your party? Would you prefer a booth of table?"
It's going to go something like that. Let her say it all for christ sakes!! Don't just walk in the door, flash two fingers while saying the word two like your spitting at her! She's asking you important questions that she needs to know to do her job properly! If you do this, the first thing she's going to do is warn your server your cranky or mean.
Now lets pretend the host or hostess didn't ask you if you prefer a both of table. When they are taking you to where they are going to seat you, do not stop and point or say "Oh I want this right here." That is rude. They are taking you to a certain table for a reason, not just because they feel like walking all the way over to the other side of the restaurant. Unless you are elderly or injured, let them seat you where they are going to seat you. When you stop and tell her where to seat you, you are messing up the rotation of seating. This means a server who should have gotten sat, now isn't because you just can't be happy with letting the hostess do their job.
Thats it for Lesson 1, look for Lesson 2 tomorrow!
