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.
Never tip salaried staff or those on commission, such as a salesperson in a furniture showroom. Do not tip the person who pumps your gas. The cost of full service gas includes the effort of the individual. There is no need to tip for furniture delivery because delivery charges are included in the bill. However, if the delivery is unusually challenging or you want to thank the individuals for terrific attitude or speed, then tipping is appropriate. A flower delivery person also does not get a tip, unless they have made a special effort.
