The obverse legend, like other French coins, gives the kingâs title as Francorum Rex ( King of the Franks  in Latin) and provides another reason to call the coin a franc. Its value was set as one livre tournois (a money of account).
Favor has a no-tipping policy from company to restauraunt, so those waitstaff that take your order pay out the kitchen (they have to pay out a certain percentage of their total sales) for you to not tip. They pay the kitchen to make these orders and make no money, unless you tip out of pocket.
Good carryout service calls for a tip. If you drive to the restaurant and go inside to pick up the food, there is no need to tip. However, if someone brings the food to your car, you should tip 10 percent. Tip $2 to $5 for pizza delivery. A tip of 10 to 20 percent is appropriate for delivery of all other foods to your home.
