I don't know. As a member of the freemarket faithful I think people should see the real costs of everything, obscuring it does not help anybody make more rational choices.
It is like tax withholding - that should not be a thing, people should be made to write a check or setup an ACH for the full amount of their taxes owed. People who are expected to actually owe more than few large, should pay quarterly estimated taxes. I think it would change a lot of peoples opinion about the value of government services. The current system is just a scheme to split the payment up into multiple places so as to obscure what the real bill is.
The expansion if tipping is the same nonsense, now historically couriers have been tipped which is what these people are. However we have gone to the expectation of that being restaurant style tips of 15-20% sometimes more! As if they have been hovering over me keeping my water glass full, and bringing me anything else I might need for the last hour. A tip should be an actual tip - "thanks for being on time, here is some $(candy bar money) for the effort). It should not be 20% of the total just for doing the job in the case of a delivery person. If it needs to be that to make it worth their while, I think yes they should be paid more, and that should be reflected in the quoted delivery fee!
For actual hospitality workers, wait staff, concierge, guides, trainers, etc - sure tipped wages make sense, a lot of what the consumer is paying for is between them and that staff member and has little to do with the house. So tips should be significant and expected when reasonable service is offered. A delivery is not that, the expectation from the outset is item is supposed to be arrive at $place at $time. A door dasher is really not different from the FedEx guy, and I don't think they get many tips. As a consumer my entire relationship with them is "Here is your package", "Ok thanks". Door Dash *should* be paying them enough to make the work worth their time if I tip or don't. I know they don't and I do tip as result, but no it does not make sense for tips to be more than handful of percent of the total comp a delivery person makes.
