completely different argument. Tipping is the normal etiquette in USA. Restaurant owners and managers calculate servers' base salary by figuring in tips. Unless that practice is outlawed, servers will need tips to make a livable wage. If tips were outlawed, then it's safe to assume that cost of food/service at restaurants will go up by 15-20% across the board, all else being equal. My point was that if a person cannot afford to dine at a restaurant in a universe where tips are included in an already expensive meal, they cannot dine in a universe where tips amounts are up to the customer. Either way, the customer should expect to shell out $700*1.15 to $700*1.2 for this dinner.
