I suspect it varies a lot by area. My rent has gone up by about $150 since I moved to my current place. Significant, but still under 20% in 4 years.
My food costs have increased by well over 50% in the same period, despite drastically restricting my diet and generally eating much worse due to diminished availability of produce.
It’s a percentage because the $60 steak was assumably at a nicer restaurant where you received more in depth service.
Fine dining servers may only have a couple of tables at once, or even for the entire night. You’re paying more for more individual attention.
It also scales in reverse. A server on a shift with a $10 blue plate special will probably have 10 tables before things go off the rails. They’ll also put serious work into getting your ass off that table the minute your plate is clean.
