Not issuing bags to the contractors seems like a bad business model.
Using a standard supermarket freezer bag makes a HUGE difference.
I don’t understand how it’s not a hard enforced requirement by doordash, Uber eats, etc. It’s nuts. I have seen it more common in other countries where it gets colder. They’ll have branded delivery bags. Though more often they are also bike couriers rather than cars.
Especially since they so often drop two orders now.
