Yes and no... we might reach an equilibrium where the level of customer service just increases. Visit Japan and then come back to the USA- American companies treat their customers like cattle (or cow pies).
I'm pretty sure the service level is a function of culture (e.g. ones upbringing), payment vs expectations in ones job, overworking, stress and so on. I think hoping that a viral video will change anything about that without a change to the mentioned things is all washed up.
In Japan the customers tend to behave far better as well. I'm sure that contributes.
