Lady expected 150 dollar tip for delivering a pizza, cried when she didn’t get it. Don’t worry though, an antiwo simp came to save the day!

That's when you hit them with the "oh you did? I'm afraid it didn't go through then, there was no tip on this order. I'm so sorry about that, it happens sometimes. So many orders coming through that the system loses the tips. If you'd like I can call the store to see if the tip went through and it just isn't reflected on my side or you can put the amount you wanted to tip on the receipt here and what the total should be and we'll make sure it gets added in properly. If the tip did go through but didn't get reflected on my end the total on their end should match what you put on the receipt and if not we can easily make sure the proper amount gets reflected." Force them to confront the fact that you know they didn't tip and either tip you or double down on their bs.

Also similar to this I had a guy in a motel that placed an order for cash payment but he was a dollar short when I got there and I refused to give him the food since that money would come out of my pocket. He claimed to have been told a different total when he placed the order and told some story about how he had to walk all the way down to "the bank" (no nearby banks and it was slow so there wasn't a massive wait between him placing the order so that's a lie) and withdraw money for this. His order total was just under $20 so his story was basically that he went to the bank to get money and withdrew $19 from the atm... Then he tried to convince me to just give him the food even though he was short and eat the cost. How did he do this? by saying that he's not short by that much and he'd been ordering from us the past few days and he tipped his driver well each time. The thing is I was the one who'd delivered to him the previous day and he paid exact change so I know for a fact that he didn't tip and the other two days he claimed to place orders on were days that we were closed because we have no one to work those days.
