Last night, over a boozy dinner, my partner and I were loosely discussing doing this a couple of evenings per week. Our discussion came from watching the delivery drivers coming in and out of the building and all looking quite happy with their lot .... jovial banter between them being the clue.
Then he spoiled it by pointing out it would be short-term thing as it won't be too long before drones are delivering direct from eateries.
Still, it gave us food for thought (pun intended) as we'd do it together - me driving, him delivering - with an audio book to focus our attention. The idea would be any funds made would go towards additional holidays.
I think it's a much safer gig these days as delivery people now rarely handle cash with everything being ordered/paid for via apps.
