Suppose I'm checking out of my hotel room, the housekeepers have done a good job, and I realize I have absolutely no cash on me.
It is acceptable to leave a little note with my phone number and "text me with your Venmo or PayPal info so I can tip?" Or something to that effect?
So a couple times a year, I have a cookout. The last 2-3 times, a guy I invited has arrived right when we were wrapping up, and it was awkward. Like, the cookout started at 6, he rolled in at 9pm, everyone had gone home, we'd put away all the food and were moving the folding chairs off the deck etc.
Is it acceptable to shoot him a message to the effect of, "We'll be starting around 6 and aren't going to go super late"?
I should mention he is an acquaintance as opposed to a close friend. But other than the above issue, I'm happy to have him on the guest list!
