Man,
I've been through the same scenario at least a couple times. All the way down to everyone sitting out. I've also been really chatty w/ ATMs like you mention. I even say shit like, "Damn, I got lucky to hold up there," as he paid off for the 1,000th time. I've seen all of the things you mentioned, just maybe not ALL at the same table.
The only difference, I feel no guilt.
