Little Caesar, you can order a pizza online for cheap (around $7 USD) and pick it up at the store without talking to anyone.
You pay with credit card over the internet, so you don't have to hand over cash in person.
You pick the pizza up at the oven at the front and can wait outside, looking in, until there's no one at the counter and then run inside and pick it up before anyone sees you. (But enter a code which takes five seconds at most)
Plus, unlike delivery, there's no anxiety of waiting for the pizza to arrive at your house.
The quality of the pizza itself doesn't matter because I eat to not feel nauseous from empty stomach, not to taste food.
But I don't eat pizza often because of lactose intolerance.
