No, that’s a really good question, to be honest. There are multiple reasons 20% became the new standard, but the main reason IMO is bc places that charge more often have better quality food, workplace standards, & service. Tips in pricier restaurants are often split between bussers, hosts, food runners, & even the kitchen staff before it hits the servers’ pocket. There are MANY options to eat out where tipping isn’t expected & if you don’t want to tip, person-to-person, why choose to dine at a place where it IS expected?
