Tipping on to-go orders and that moment of regret

Money saved is money earned. And money tipped, well, that’s money gone. And, Winstead’s, I wish I had my $5 back.
I get it. I asked for 12 sandwiches. That’s a large order. That’s why I was glad to leave a tip. However, that was before I had to tell my father-in-law that he didn’t have a burger because we were one item short. I didn’t check the bag. That’s on me. I left you a tip. That’s also on me. But the regret I feel? That’s all yours, Winstead’s.
