Your experience with theft by delivery boys?

(I know there are women doing deliveries now a days too, but it's rare enough. Saying delivery partners might cause confusion, so sticking with delivery boys.) I was chating with a cousin from Delhi (keralite but IIT Delhi student) about his frequent food thefts by Swiggy/Zomato delivery boys. In fact, most family and friends from Bangalore and mostly northern states occasionally tell me this. However, I can't relate. I've been using Swiggy/Zomato for years and if anything was missing, it's usually resturants fault. As someone from Trivandrum, have you experienced any thefts form delivery boys? Am I just lucky? Or Trivandrum delivery boys risk averse and just wants to do job honestly and get paid without drama? Similarly, I'm hearing about Flipkart's open box delivery scams too, but everyone who delivered to me here in Trivandrum has been professional and honest. 😲 How's your experience?
