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.
Another rule of thumb when it comes to tipping â be discreet. Donât wave big wads of cash around to impress your friends or staff. Subtlety is key. And even when you receive poor service, you should tip something, even if itâs only a small amount.
