I ran into a college friend this week who I hadn't seen in years. We decided to have breakfast at a local popular breakfast place in the Gold Coast.
Before we knew it, almost 2.5 hours passed. We were definitely lingering, unless you consider numerous coffee refills not lingering. The waitress at no time seemed to rush us or be bothered that we were taking up a table (a 4-top for the two of us).
I left here a 50 percent tip. I think that was fair.
