100 degrees out. People are ordering 4+ packs of water to upper level apartments with no tips. Express Shopping no less...

I'm not one to complain about no tips, but stuff like this is downright disrespectful. I live in a part of the US where we go decades without breaking 100 degrees. It's about 96 degrees with a dew point in the 70's. Who in their right mind thinks it's morally acceptable to order Express Shopping for groceries plus four giant packs of water bottles to an upper level apartment (without an elevator) and refuse to leave a tip? You have to intentionally put $0.00 for a tip in the app. It prompts a minimum amount.
