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.
Please do not confuse this fee with the tip. You should tip the same as you normally would. The fee is a surcharge on your bill for the store and not given to the driver. In national chains like Pizza Hut, Domino's, and Papa John's, the delivery charge does not go to the driver's tip. It is a disguised price increase for the store.
