Input: I've been sick the past few days and decided to order groceries delivered. I've used the app a few times before with no issues, and always tip 20%. I ordered about $50 worth of stuff included 3 12-packs of ginger ale. It goes as normal, and they came to my door with the bagged stuff and said they had 2 sodas downstairs and 1 more in the car. I figured ok, and bring in the other stuff while waiting for a knock. 

&amp;#x200B;

However they never came back. The app lets them text/call me but they didn't. There's no locks or anything that could lock them out. After a while I go downstairs and the 3 packs are tucked back under the open staircase. I guess they didn't want to bring them up the flight of stairs? There's no long hallway or anything, it would have been just upstairs plus 10 feet to my door. I know bringing them upstairs is a pain but that's why I pay for delivery and tip. I want to go back and delete my tip but my roommate thinks it would be a jerk thing to do. However I had to go out, find them, and haul them up myself, while sick, and they just ghosted me. Am I the jerk here?

not tipping when they didn't deliver half my order
