15% at a breakfast restaurant isn't enough!?
I had breakfast at Frans in Toronto. My table was about 6' from the kitchen. My food was prepared quickly and I ate quickly. The waiter never even refilled my water. I was probably in the restaurant for 30min or less. Basically a super easy interaction for the waiter. I tipped 15%, he went to the next table 2' away and complained to them, and asked if he was a good waiter and said he deserved a larger tip!
