The "expectation" of tips making up the rest is really just an expectation from the business that you will needlessly subsidize their payroll, in all 50 states the employer is mandated to always pay the minimum wage even if zero tips are earned https://www.dol.gov/general/topic/wages/wagestips

I say tipping is unnecessary because there exist a few states like California who ban the practice of paying a lower "cash wage" and allowing businesses to keep tips for themselves. Anecdotally, I notice that typical restaurant bills in California are not any more expensive than nearby states like Nevada, Colorado, or Arizona.

I say tipping is necessary, for me, because it helps people out.
