When Lou Malnati's frist came to my area, I went and gave it a try. Ordered their "largest" pizza which was about 10" in diameter. Anyhow, no toppings, just cheese for pick up. IIRC it was somewhere north of $30, then tax. I went to pay and she flipped the screen around with the pre-set tips amounts of like 20-40-60 percent.
What? Exactly how much should I be shelling out for a cheese pizza? And this was BEFORE inflation was kicked into high gear. Didn't live up to the hype, never had a desire to go back, that didn't help.
Tip when someone does their routine job.
