Many services... Maid service in hotels and hotel services in the industry as well. Taxi/goods delivery(not just food, but things like target 2hr delivery)....

I'm not saying it's good... And I think the fundamental problem exists in these jobs as well... Typing should just not exist. Japan, for example has no tipping... It's ducking fantastic.

My point has nothing to do with whether a practice is good or not. It's about how deeply entrenched the practice is, and the practical complexities of uprooting the practice. Bad practices still require significant consideration in undoing.

My point is that "we should do away with ___" is an impotent sentiment by itself. Who is we? How are "we" going to actually do it? What does the transition period look like? What are the consequences? These are questions that, pragmatically, must be taken into consideration when implementing any large change, totally independent of any value judgement of that change.

Again, this "argument" is totally irrelevant, but:

If that counts the same as TSA, then hair/nail stylists, massage therapists, valets, Uber (and taxi and limo) drivers, hotel housekeepers and concierges are all traditionally tipped.

But again, that doesn't matter. The system is what it is. Changing it is an option, but that does have practical considerations associated with it.
