That's not the issue, imagining driving through a roundabout that curves left and having to find a button somewhere on the steering wheel, which is at an angle, in order to indicate right before turning tight in order to exit the roundabout.
A stalk will always be in the same position. The same cannot be said for buttons.
I payed the establishment for the service. The barber is payed a fair wage by the barbershop and did exactly what his job requires. Why is a tip necessary?
Wtf is the s?
