It is an almost foolproof FIFO pipe (literally), simplemfor everyone to understand and very cheap to run.

I did not leave a tip.

The stressful and annoying payment dance at the end of a cab ride was a not-insignificant factor in the rise of ridesharing.

Why should employers pay employees when their customers can do it for them?

Or so I was told. I saw it more when I was younger than I do today.

Generally, most tipping is at restaurants and bars/pubs. Hairdresses/barbers/salons is also very common because of the close personal interaction with the worker.

Most of the time you tip at businesses that would be expected to employ low-education, or poorer or immigrant workers (and by extension, more easily abused workers.) Restaurants, salons, car washes, etc, all tend to employ poorer, less educated people, and also tend to be highly tip-based businesses. So for the most part you're expected to tip at businesses that traditionally abuse and underpay their employees.

But in the USA, it is not uncommon to see Budlight selling for 8 dollars or more. (don't forget to tip!)

If they weren't using the same currency there would probably be difference in inflation due to very different economics between let's say New York and some tiny rural village.

Really? I never know anyone doing this

In the US, yes.

People I regularly tip: - wait staff - barber - delivery service (for oversized packages/furniture delivered into my home, not general UPS/FedEx deliveries that are left on the doorstep) - taxi driver

It's a side effect of a low minimum wage. Most of the rest of the western world has the minimum set closer to a living wage.

But why taxi drivers? Why delivery drivers? Are those groups also poorly paid because they rely on tips? Why other social groups haven't adopted this? Are your electricians also charging $1 an hour of work and then expect that you leave a tip that saves them from poverty?

Does not happen nearly as often since Uber is squeezing them though.

Though I'm already thinking about how maybe the balls need some sensors or we codes so we can have data and a dashboard.

I firmly believe that queuing is the very basis for, and perhaps definition of, civilization itself.

(British, can't you tell?)

:D

This way I both struggle myself (as I never want to go there that early) and harm the others' comfort and convenience by occupying the place, making the queue longer. People also tend to conflict, fighting for their place in the queue (I had to witness and to participate in too many queues in my life, people become nasty there).

If I know it's random I come whenever I'm comfortable.

Meaning you still wait the same amount of time on average, just have a bunch of "that was quick" and "wtf. I'm waiting for 4 hours" thrown in there. Not an improvement if you ask me.

Would you pay more to guarantee getting the highest rated driver near you?

I haven't had a "bad" experience, but I've had some better than others.

Part of Uber Comfort's value proposition is that only highly rated drivers are allowed to participate.
