French rules of dining etiquette - what another one?

"Where do I out my cell phone, the left or right side?"

Yes, Being in France, there is a strict code of rules on how to behave; it makes life here so much more pleasant..

Please remember, When you are offered something ( like a fill up of your wine glass, more bread, a minor treat) simply saying 'Merci' indicated a refusal, as in "No, thank you". This is quiet different from the American practice, were saying a simple 'Thank you; implies acceptance, as in 'Yes, thank you.'
SO - in France, if you want your wine glass filled or more bread, don't say 'Merci' 
    SAY - 'oui, s'il vous plait"
