Depends. 20-30% if you are dining solo and not drinking in a place which is normally couples and with some wine, seems fair, since what actually matters to the waiter is total tips at the end of the night. My check is probably $40 vs $120.

You are also less work for them. I'm not sure why you feel obligated to make up for the fact that you aren't blowing 120 dollars at the table.

I'll tip 30% at like an Ihop when my bill is 11 bucks because "total tips" is what matters.

They get a finite number of tables in an evening.
