quicko: to tip

I must admit, I was shocked and appalled with myself the other day. When I was in Grand Rapids with Holly, we stopped in at Steak 'n Shake (things you won't see in Australia, part two!) for a late-night dessert and, after we paid, I watched Holly walk back to the table. Thinking she'd left something, I half followed her until I figured out what was going on: she was, as every American does, leaving a tip! And I'd completely forgotten! And I've even been a waitress!! Thankfully it wasn't too late for me to leave my 15% as well, but I was absolutely shocked and appalled that I had come so close to neglecting to leave a tip. I guess I have been away too long!
