Do you agree or disagree with Mr. Pink's attitude on tipping?

I respectfully disagree with this. Mainly for the reasons outlined in the monologue:
- It shouldn't be an obligation, it should be given by choice if the customer thinks it's deserved
- Why is it reserved for some professions and not others, where do you draw the line
- If staff are relying on it to supplement their income, that's part of a much larger problem, that shouldn't be the customer's obligation to fix

For the record I do live outside the US where tipping probably isn't quite so ingrained in the culture
