Business meeting etiquette

From a business etiquette presentation at work I found. Seriously, who comes up with this crap?????? So these are guidelines in case you go out for dinner with some clients:

Napkins:

When to pick up? 30 second rule.
Where to place when excusing yourself from the table mid-meal?
Where to place when you're through eating?
Place on seat of your chair or left-hand side of place setting when excusing yourself from the table
Place napkin on right side of place setting when you're finished and leaving the table (because we all know that left handed placement is wrong, wrong, so wrong)
Question: Is it acceptable to ask for a different color napkin at a restaurant? (who has ever asked for a different colored napkin? wtf?)
Do Not

Push your plate/chair away when done
Reach across the table
Use toothpick publicly
Season food before tasting (why is this in bold? why can't you season food before tasting? i don't know about you, but i like pepper on my mashed potatoes!)
Blow, pop or crack gum
Put on make up at the table
Blow your nose at the table
Ask for a doggy bag
Blow on your food to cool it down (they must prefer you to burn your mouth on food instead)
