I was picking up sandwiches from a local shop and watched 3 doordash/Uber Eats drivers come right after the other to pick up the same order, but they all cancelled it because the restaurant didn't have multiple deliveries for them to pick up at the same time- ie- they were dropping off multiple houses each run. It made me realize why the food was cold last time we ordered from them! From now on I just go and pick up myself.
