There is nothing like realizing -- too late -- that when the delivery guy brought in the oversized box containing something-or-other you've ordered, and you asked him to lean it against the wall in the living room, that there was a rack of your bras and panties drying right next to that same wall and the delivery guy definitely got himself an eyeful.
Getting a euro for lugging a big box up 3 flights in the elevator? Would have been nice. Getting a peek at my zebra-print panties? Priceless. So yes, dude, that glimpse WAS your "tip". Have a nice day.
