To everyone acting like tipping rules are written in stone, let’s talk about it.

I had a $612 dinner bill, and suddenly I’m “supposed” to leave over $120 just because the total was higher? Same plates carried, same drinks refilled, same amount of time at the table—but somehow the menu prices decide the server’s pay?

I left $9 That’s still real money for a couple hours of service. But the mood shifted immediately, like I’d broken some unspoken law. Then the manager came over talking about “industry standards,” as if that settles the whole debate.

Since when does a more expensive meal automatically mean more effort? If I order a $50 entrée instead of a $20 one, does the plate suddenly weigh more?

I do tip for good service. But I don’t think a tip should automatically become a percentage-based surcharge just because the restaurant charges more.

So honestly is that fair, or have we just gotten too used to it to question it?
