FirstWatch tipping

This was a first for me, maybe I’ve just never noticed before?

I went to FirstWatch with a friend for brunch today. They split our bill and we didn’t even have to ask. I paid first at the cash register and it prompted me to tip. I chose 20% which turned out to be $10.44 on my $24.27 dollar tab. Hmm. When my friend paid her $27.97 tab, it prompted her again for a 20%, $10.44 tip. They played dumb but are most certainly aware that when they split tabs they are prompting each person to tip on the entire bill which was $52.24/$10.44.
