Individual service persons should not be held hostage to your interpretation of their service for their wage. If they're routinely underperforming they'll be sacked.
Tipping can still take place. It just doesn’t need to be obligatory. It’s the difference between a culture of servitude vs a culture of service.
Although I'd never pay $25 for a burger. (Sydney here)
I remember being particularly unhappy about being served breakfast in Houston while I was there for a conference and being referred to as "sir" - I almost asked the waitress to stop but I realised that would probably cause even more problems so I stayed quiet.
So I would reject the idea that the service in US restaurants is somehow fundamentally "better" than elsewhere - it's just different and some of us actually regard that style of service as a negative.
Grilld is a popular mid-range burger chain and their burgers range from AUD $9 to $16.90 (USD $6.60 to $12.40). All advertised retail prices in Australia include 10% GST (good and services tax).
At a more formal restaurant you will likely find a AUD $25 burger but that's about the top end for burger prices.
As an American living in Australia, I really do miss tipping. I think that on average the restaurant service here is a lot lower. At most restaurants at the medium level (e.g. $25 hamburgers) you pay in advance, and then a waiter will bring the food to you when its ready. Do you need more water? Get it yourself... Ketchup, you have to ask but it won't be offered. The waiters don't care because they are making good money anyway. The only place you get American style service is at the very high end places.
