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.
Some pizzerias publish âhelpfulâ tip guidelines stating that $3 is the minimum standard tip on any delivery order less than $20. Three bucks is about 15% of $20 and sounds fair for most situations. A $10 order is just as much delivery work as a $20 order, and a $3 tip is not unreasonable. If you have a huge order, special requests or additions (like a case of soda) included in your delivery, you might want to up your tip percentage to 20-25%.
