Dunn's:

We have walls that roll up so it's like open on the sidewalk basically but there are also huge barriers like this tall, half-wall thing. These kids younger than me got 1 poutine to share and didn't tip me and then camped in my booth so I was pissed but then this robber guy with a shaved head runs up, reaches over the gates and jacks the kid's backpack.
The kid cried out, "my backpack!" and this other kid, not my table, jumps up and chases the thief down the street but comes back later, empty-handed. That's what you get when you don't tip. I laughed.
