Simple solution, Uber Eats. Give the waitstaff a break from those who consider them lower class.
Since Uber Eats prices are listed at a higher price, customer happy that no tip is required (even though the price is 15-25% higher than eating in).
Zero tip to Uber not a big deal, (they know where you live)
.
I bet most will eat right out of the container instead of plating. Win for all
