under normal circumstances, you're usually not home when the postman brings your mail. some people give their postman some cash if they happen to run into them, especially if it's around a major holiday.

as a random anecdote, I was talking to the ups delivery guy for my building the other day, and he said he's been making more money in tips than from his actual paycheck during the present crisis.

My postman mostly brings me junk mail, that I throw directly into a bin next to my building's mailboxes rather than bring it up to the apartment. That's not his fault, of course. There's no mechanism for me to tip him on any regular basis, unlike the delivery apps that let me add a tip to my credit card payment.

Every Christmas. The UPS guy too.
