stop eating out or ordering in if you don’t like the tipping system

It's that simple. Stop railing on those that rely on tips. We all are stuck in this Capitalist Hellhole and have different lives. You do not know what's going on in people's lives and why they are where they are, doing what they're doing. Maybe go read some r/talesfromyourserver to see examples of what people deal with regularly and why.
